I just purchased an Accushadow 2 and I'm realizing it is very particular with regard to ammunition. What ammunition are people using in their Shadow 2 pistols? Will all 124 grain FMJ fit? Are there any 124 grain FMJ that do not fit?
-
Welcome to the forum! I too just purchased an Accushadow 2 that I'm building a carry optic rig with at the moment. CZ's have a "tight" chamber that is designed for 124gr ball ammo. If you are purchasing bulk ammo you may want to verify it will chamber in your barrel first (take your barrel with you to the store and verify it will pass the plunk test). There is a ton of info in the sticky here: https://czfirearms.us/index.php?topic=114236.0
Cheers,

Welcome aboard !
You shouldn't really have trouble buying factory FMJ ammo or reloading your own FMJ ammo for your Shadow. CZ's are more particular about their ammo than a Glock or a Ruger, but 99% of the issue is going to be with strange bullet shapes (like conical or JHP) or strange bullet weights (like 147gr) that are not sold in Europe.
This is all detailed in the Stickies you've already been directed to. There are 2 sections, 1 for purchased ammo and 1 for home reloads. The information there walks you through the whole process. When you finish digesting one or both sections, if you still have questions, we'll be more than happy to go into more detail. But there's so much info there that it's not worth repeating here.
We will wait on your questions.
All the best.

Thanks for the replies. After researching the links it seems that any 124 grain FMJ should be fine. I had planned on using 130 grain FP but only half of the cartridges passed the plunk test. I'll shoot the 130 grain through my Sig and stick to 124 grain FMJ for my CZ. Thanks again.
-

This statement is unclear. You plan to LOAD 130gr or you plan to BUY 130gr ??
I shoot 135 and 147gr all the time in my stock SP01, but I reload them myself.
Federal also has a 135gr self defense round that chambers well in the CZ.
-
Federal Syntech 130 grain PCC ammunition produces a power factor of around 130 using a 5 inch barrel. Since I don't reload and prefer a flat nose bullet for knocking down steel I had planned on using that in the Accushadow 2 for USPSA competition. When I did the plunk test using my Accushadow 2 barrel only half of the rounds passed. After researching a little more I also learned that the Accushadow 2/Shadow 2 prefers round nose bullets instead of flat nose bullets. I'm therefore now looking for 124 grain FMJ to use in my Accushadow 2.
-
Both the Blazer Brass 9mm 124 grain RN and the Freedom Munitions 9mm 124 grain RN (new) passed the plunk/fall test with my Accushadow 2 barrel. To do the test, I drop the round into the barrel and listen for the plunk sound. I then turn the barrel upside down to see if the round falls out of the barrel on its own. 100 rounds of both of these passed the test.
I shot 100 rounds of both of these with no malfunctions of any kind. At 5 yards shooting 5 rounds freehand, the Blazer Brass had a 1 1/2 inch group with 3 shots touching and 2 shots touching while the Freedom Munitions had a 1 1/4 inch group with 4 shots touching and 1 outlier. Without the 1 outlier the Freedom Munitions 4 shot group was 7/8 inches. I'm sure the accuracy would be better shooting off of a rest, but I wanted to know what my accuracy would be. I was very impressed.
-
...... What ammunition are people using in their Shadow 2 pistols?.....
Personally, ....my 9mm reloads. 124gr bullets of various manufacture over Vihtavuori N310 & N320 powder. The matches I shoot, power factor is not an issue so my goal is the lightest possible recoil that will still allow the pistol to function reliably.
When performing your "plunk" test, once you drop the round in the chamber check to see that you can turn the case without resistance of the projectile ogive. Turning the barrel upside down and allowing the round to drop free doesn't tell you much other than gravity is still a viable law.

Respectfully, I disagree.
Dropping the cartridge into the chamber....
1) one can have the tendency to lay a finger on the primer inadvertently to "assist just a little", or
2) the momentum of entry can wedge things at the last moment.
By dropping back out of the chamber, the cartridge can only be using its own weight. It proves there is no wedging and there's no was errant fingers helping things along. So dropping back out is a very useful second part of the test, especially for novice reloaders who are trying to perfect their process.
Just because you choose not to conduct a full test doesn't mean our method is invalid.
-
Could you clarify the full test process if you would? I’m uncertain when and where the “spin” portion of the test comes into play, or if it is even included in the full test process. I’ve read all the “stickies” and there was no mention I could locate concerning the requirement of inverting the barrel as to allow the round to drop out of the chamber under its own weight. Thanks.
-
My plunk test I drop the round into the barrel, spin, and then turn the barrel upside down to drop the round out of the barrel. It's not always easy to tell if the round is spinning or if my fingers are slipping, but it's easy to tell if the round falls out of the barrel on it's own.
I recently plunked 100 rounds of Eley Minor 9 ammo. Every round dropped into the barrel with a solid plunk sound. Spinning was questionable, and when I turned the barrel upside down each round did not fall freely. When I shook the barrel a little the rounds would fall out, but it took a little shake to get them to fall. It seems the bullet is just barely touching the rifling. I will shoot them tomorrow and don't expect any issues, but I won't be buying anymore.

You're quite correct. No single document contained all the pieces. That has been corrected in both the Buying and Reloading directories. Thank you for pointing that out.

I shot 100 rounds of Eley Minor 9 124 grain with no malfunctions. It plunked when dropped into the barrel but would not fall out of the barrel without me giving the barrel a little shake. At 5 yards shooting 5 rounds freehand, the Eley Minor 9 had a 2 inch group with 4 shots touching and 1 outlier. Without the one outlier, the 4 shot group was 1 inch.
Given that the Eley Minor 9 rounds did not fall out of the chamber freely and the cost ($22.30 per box plus shipping), I plan on using Freedom Munitions 9mm 124 grain RN (new) ($13.90 per box plus shipping). The Freedom Munitions accuracy was slightly better than the Eley (most likely the difference was because of me) and I couldn't feel any difference in recoil between the Freedom Munitions (1065 fps) and the Eley (1050 fps).

This is a danger sign you need to pay attention to !
Typically, when you get those results the case is properly proportioned, but the OAL is too long for the CZ's short leade. The bullet is then wedging itself into the rifling, which is what's retaining the cartridge inside the chamber. This will typically defeat the "spin" portion of the "Plunk & Spin" test.
The danger is that if one of the cartridges happens to be 0.008 to 0.015" longer for any reason, then the slide does not go completely into battery. The trigger is allowed to drop the hammer, but the slide is not locked. Then you get accidents that look like this...

Of course, your Shadow may not be plastic, but the spewing of brass bits at 30,000 psi is never good for the human.
-
Thanks, Wobbly. I'm not buying anymore [Eley 124gr]. Given that it was barely touching and it's a low pressure round (1050 fps) I felt it would be low risk to use up the 100 I bought. I also had plunked each round, so I knew each round would seat correctly and not be out of battery when I fired it. Even though I fired all 100 without any issues, I do not recommend the Eley Minor 9 for Shadow 2 pistols. I won't be using anymore.
-
I just received a case (1000 rounds) of Freedom Munitions 9mm 124 grain Round Nose (new). One bullet was setback/damaged and not usable. All of the other rounds looked good.
-
Precision One has competition 9mm 124 grain ammo for $13.99 per box ( https://precisiononeammunition.com/product/9mm-124gr-fmj-remanufactured-competition/ ). Has anyone tried this ammo in a Shadow 2? Under Description it states the bullets are X-treme/Berry's. The Freedom Munitions ammo uses X-treme bullets, so I think the Precision One ammo should pass the plunk test. I plan on purchasing two boxes to see.
-
Both X-Treme and Berry make plated bullets, which are good, but not as good as properly sized lead, or jacketed. If you're competing at a high level and need the best, then you may want to pass.
They'll be fine for practice.
-
Shooting Freedom Munitions 9mm 124 grain today I had a failure to fire (FTF). The primer had a deep indentation, so it wasn't the gun. So far I shot 350 rounds of Freedom Munitions with 1 FTF. I'll finish out the Freedom Munitions I have using them for practice, but after the FTF I had today I will not be using them for competition.
-
I plunked 100 rounds of the Precision One Competition 9mm 124 grain ammo. All 100 rounds plunked and freely fell out of my Accushadow 2 chamber. I measured the overall length of the Precision One rounds to be 1.130 inches. I'll shoot them the next time I go to the range to see how they shoot.
-
I shot the 100 rounds of Precision One 9mm 124 grain RN competition today. There were no malfunctions. They were the softest shooting rounds I've tried so far. I estimate the power factor is 132 out of my Accushadow 2 barrel. I ordered a case and plan on using them this season for USPSA competitions.
-
I've used their 135's for my last 4 matches. Zero issues out of a shadow 2. They all measure 1.13 to 1.14
-
Thanks for the info. Good to know the 135 grain will work in a Shadow 2 as well.
-
I found some other competition ammo that claim to work with the Shadow 2. Does anyone have any experience with these?
NC Shooters Supply, 9mm, 125 grain, 1040 fps (5 inch barrel), 130 PF

No help on competition ammo but I have gone thru about 1,000 rounds of Blazer Brass in my new AccuShadow 2. It was a mix of 124 and 115 gr., 0 issues. Good Luck!

I find the best place to get competition ammo is my garage. You really should consider reloading your own.

For me, reloading is a great option; I get custom ammunition for my firearm, and I save some money. I also think, however, that reloading is not for every person. Some people are not good candidates for safely loading ammunition, or would find it too much of a hassle. If you're the kind of person who is easily distracted, or likes to take shortcuts, it's not the right thing for you! I like getting to the bench and focusing on accurately measuring and producing a quality product for my pistol or rifle, it's when I put everything else out of my mind for a while.
-
Blazer, bellom ,sellier & bellot, federal American Eagle all 124 gr all run flawlessly in mine…
-
Shot a USPSA match yesterday using the Precision One 124 grain competition ammo. I shot 207 rounds with no malfunctions. Very soft shooting and knocked all of the steel down when I hit it.
-
I tried the Precision One 135 grain competition ammo, but POI is above POA for me. The POI and POA are identical for the Precision One 124 grain competition. I'm going to continue to use the Precision One 124 grain competition for USPSA matches.
-
124 ball ammo is best
-
Has anyone tried the American Eagle Federal 147gr 9mm flat point on the Shadow 2? I plan to use it for an IPSC match hoping it will have a softer recoil than the 124gr factory ammo but am concerned about feeding and jamming issues. Thanks in advance.

Welcome aboard !
147gr made by anyone is typically an "iffy" situation in any CZ handgun.

I plunk tested the Federal American Eagle 9mm 147 grain flat point rounds in my Accushadow 2 barrel. It did not pass. The base of the brass case was significantly higher than the end of the chamber. In my opinion, using the 147 grain flat point rounds in a Shadow 2 would be dangerous.
I'm using Precision One 9mm 124 grain competition ammo ( https://precisiononeammunition.com/product/9mm-124gr-fmj-remanufactured-competition/ ). They pass the plunk test, have a power factor of around 132 out of a Shadow 2, and are very soft shooting. I would recommend trying those.
-
I had a chance to chrono the Precision One 124 grain competition ammo using my Accushadow 2. The average velocity was 1099 fps which equates to a 136 PF. A little hotter than I expected, which might explain why the steel falls easily. I would prefer something around 130 PF, but I'll probably stick with the Precision One for now since I have over 1000 rounds through my gun with 0 malfunctions.
-
I've reloaded thousands of Xtreme 124 grain plated FP. I've shot them through every pistol I own, from Glock to CZ, and have zero issues. They plunk and spin in all my pistols. My recipe is 5.1 grains of CFE Pistol with an OAL. of 1.050. The PF is 136. Great round. Just my 2 cents.
-
I just received two boxes of Excaliber 9mm 124 grain minor PF ammunition ( https://excaliber-ammo.com/product/9mm-124-grain-competition-gold/ ). This ammo is USPSA certified so there are no issues with chrono. The box claims 1050 fps out of a 4.7 inch barrel for a power factor of 130. The brass is new and has a Troy headstamp. I'm not familiar with Troy brass but as long as it functions fine I don't care. The Excaliber new ammo is $18.00 per box while the Precision One remanufactured ammo is $13.99 per box. Depending on how things go, I might use the Precision One for practice and the Excaliber for matches. This weekend when I'm cleaning my Shadow 2 I'll plunk the Excaliber ammo. I'll let everyone know the results.
-

When you add a "flat point" to any bullet, then the ogive must get "fatter" or wider. It's the extra width at the ogive that gets you into trouble. Any bullet with the extra width at the meplat, such as the RH example in this cartoon, is simply begging for difficulty.
(https://i.imgur.com/O1KPgYIl.jpg)
Again, a Flat Point is a specialty American bullet unavailable in Europe. That alone should start the red warning lights flashing in your head.
-
I plunked 20 rounds of Excaliber 9mm 124 grain minor PF ammunition. All 20 rounds plunked when dropped into the barrel, spun freely, and freely fell out of the barrel when the barrel was inverted. I'll shoot them the next time I go to the range and report back my impressions.
-
I measured the OAL of the Excaliber 9mm minor PF ammunition at 1.130 inches.

You sir, think like a reloader. You should definitely consider it.
If the cartridge didn't 'plunk and spin', then a reloader could reduce the OAL to 1.120" or even 1.100" until it did. The problem with factory loads is that it's pure digital 1 or 0, Go or No-Go. But with reloads you control everything... the OAL, the PF, the primer sensitivity, the muzzle flash, everything.
You've been previously commenting on PF. Reloading would give you the option of stepping down from PF136 in increments of 1 until you were delighted with the performance.
May I suggest that you start to pick up all your spent brass.
-
You sir, think like a reloader. You should definitely consider it.
Thanks, Wobbly. When I retire I'll consider reloading, but right now I just don't have the time. From my very limited sample size, an OAL of 1.130 inches always passes the plunk test while an OAL of 1.150 inches sometimes passes and sometimes fails. I'll still plunk every new type of ammo I try, but 1.130 seems to be the magic number for 124 grain round nose.
-
But for factory ammo you have no idea if the 1.130" and the 1.150" used the same bullet. They may look similar, but the truth is that they may run a year's worth of 1.130" the last 2 weeks of February, and not run the 1.150" until 4 weeks in November. So it would be easy for the bullets to be quite different.
-
I shot the 100 rounds of Excaliber 9mm 124 grain Minor PF ammunition today using my Accushadow 2. All rounds fired without any malfunctions. There was no perceived difference in recoil between the Excaliber 9mm 124 grain Minor PF and the Precision One 9mm 124 grain competition ammo. The Excaliber 9mm 124 grain Minor PF ammo seemed to have a POI that was lower than POA using my Accushadow 2. It was not a huge difference, but shooting side by side with the Precision One ammo I definitely seemed to shoot lower with the Excaliber ammo. I'll probably buy two more boxes of Excaliber ammo to see if the POI difference is reproducible. For now I'm going to continue to use the Precision One 124 grain competition ammo.
-
POI is one of the features under direct control of the PF.
As the bullet starts to move down the barrel, at that exact same time the muzzle starts to rise. This is due to Newton's Third Law, and the torque reaction created by the supporting shooter's wrist being lower than the bore axis. So for the same weight bullet, the higher the PF the higher the POI will be on the target.
That is to say, the recoil raises the muzzle to bring the bullet in-line with the Bull. With a consistent grip... low power will end up landing lower on the target; higher power will end up with a higher POI.
You may wish to shoot 5 of each from a supported position to document results.
-
I ordered 100 rounds of NC Shooters Supply 9mm 125 grain Minor Power Factor ammunition ( https://ncshooters.com/product/100ct-9mm-125gr-minor-power-factor/ ). The website claims an OAL of 1.110 inches and 1040 fps out of a 5 inch barrel. It also says the ammunition is based around CZ chambers. 1040 fps with a 125 grain bullet is a power factor of 130. My Accushadow 2 has a 4.89 inch barrel, so it is a little shorter. The minimum fps to make power factor would be 1000. We'll see how it does out of my Accushadow 2.
-
I shot 50 rounds of NC Shooters Supply 125 grain Minor Power Factor ammunition. There were no malfunctions of any kind. POI matched POA. At 5 yards shooting free hand four bullet holes out of five were touching. The recoil was noticeably less than the Precision One 124 grain competition ammo. My splits for doubles were higher with the NC Shooters Supply than with the Precision One. While the Precision One had more muzzle rise, the muzzle also moved faster and came back on target in less time than with NC Shooters Supply. I'm still evaluating and haven't decided which ammo I like better.
-
I ordered 100 rounds of Super Vel 9mm 124 grain certified select ammo....
( https://supervelammunition.com/9mm-luger-124-gr.-fmj-certified-select-/ )
According to the Super Vel website reviews, it should be ballistically identical to the Precision One 124 grain competition ammo (1100 fps, 136 PF). Once I receive the Super Vel ammo I'll shoot it side by side with the Precision One ammo and see if I can tell a difference.
-
I received my 100 rounds of Super Vel Certified Select (remanufactured) 124 grain ammunition. I measured OAL at 1.110 inches. There were no setbacks or any visual defects. After inspecting the 100 rounds my hands were dirty, but that's not a deal breaker for me. I'll plunk them this weekend and see how they do.
-
I plunked the 100 rounds of Super Vel Certified Select 124 grain ammunition today. All 100 rounds plunked and freely fell when my Shadow 2 barrel was inverted.

Then it sounds like they should be safe to fire. Adjust the hammer spring for 100% ignition, then adjust the recoil spring for slide-lock-back on empty mag... and you'll be there !
-
I shot 50 rounds of the Super Vel 124 grain Certified Select ammo today. There were no malfunctions of any kind. I alternated between the Super Vel and the Precision One and could not feel a difference between the two. My split times and accuracy were the same. I plan on using either one for my USPSA competitions.
-
After trying many different types of ammunition, I have come to the conclusion that the best ammunition to be used in my Shadow 2 for USPSA competitions uses a 124 grain bullet travelling at 1050 fps out of a 4 inch barrel (standard barrel length for fps measurement). This results in a velocity of ~ 1100 fps out of my 4.89 inch Shadow 2 barrel resulting in a PF of 136. I have tried ammunition that is both faster and slower than this, but 1100 fps gives me my fastest split times. I will continue updating this thread as I try new ammunition, but I will be focusing on ammunition that travels at 1050 fps out of a 4 inch barrel.
-
Congrats on the Accushadow 2! It's a sweet pistol. When I first got mine, I went through a trial and error phase with ammo. Found that most 124 grain FMJ rounds worked fine, but there were a few brands that didn't quite fit smoothly. Ended up discovering a great deal on cheap ammo through ammobin.com (https://ammobin.com) that worked like a charm. It's worth trying a few brands to see what feeds best for your Shadow 2.

Do you remember what brands didn't quite fit smoothly? That would be good information to know.

Precision One competition ammo is now USPSA certified ( https://uspsa.org/ammunition ).

Super Vel has 9mm 124 grain ammo using new factory brass ( https://supervelammunition.com/9mm-luger-124-gr-fmj/#reviews ) that is supposed to be ballistically identical to the Super Vel 9mm 124 grain Certified Select (remanufactured) ammo. I shot 50 rounds of the new factory brass ammo and could not tell the difference between the two. There were no malfunctions of any kind.

My wife gave me a Garmin Xero C1 chronograph for Christmas. I was able to chronograph the Blazer Brass, Precision One Remanufactured, Super Vel Remanufactured, and Super Vel New (all 124 grain) today. The stated velocities in fps of these rounds are:
Blazer Brass: 1090
Precision One Remanufactured: 1044
Super Vel Remanufactured: 1050
Super Vel New: 1050
I shot 10 rounds of each using my 2022 CZ Accushadow 2 (4.89 inch barrel). The low, average, and high in fps for each one were:
Blazer Brass: 1091.0 1117.3 1135.8
Precision One Remanufactured: 1046.3 1075.8 1099.9
Super Vel Remanufactured: 1034.6 1068.6 1095.1
Super Vel New: 1035.8 1071.4 1085.4
No big surprises. The velocities were greater than advertised due to the barrel length. The Blazer was about 50 fps faster than the others and the Precision One was about 5 fps faster than the Super Vel. This all tracked with how the ammo felt when I shot it. The low, average, and high power factors were:
Blazer Brass: 135 138 140
Precision One Remanufactured: 129 133 136
Super Vel Remanufactured: 128 132 135
Super Vel New: 128 132 134
Even the lowest velocity of the 10 shots for all of the ammo met the 125 power factor USPSA minimum, so any of these would be acceptable for USPSA.

Thanks PA USPSA,
This is very informative.
-
You're welcome. I plan on testing additional ammo as money and time permits. For an ammo that I haven't tested before, the test will consist of plunking at least 10 rounds, chronographing 10 rounds, shooting 5 rounds freehand at 5 yards, and general impression of the ammo. After shooting at least 50 rounds I'll report if I had any malfunctions.
There's a lot of competition ammo out there, so I think I'll be able to do this for a while. I'll start testing the ammo that I can get in 50 round boxes and then work up to ammo that is sold in higher quantities. Stay tuned.

The website claims an OAL of 1.110 inches and 1040 fps out of a 5 inch barrel. It also says the ammunition is based around CZ chambers. 1040 fps with a 125 grain bullet is a power factor of 130. My Accushadow 2 has a 4.89 inch barrel, so it is a little shorter. The minimum fps to make power factor would be 1000. We'll see how it does out of my Accushadow 2.

I purchased a 50 round box of Atlanta Arms Classic Match 9mm 124 grain ammunition. This is new brass with an advertised velocity of 1060 fps and an advertised OAL of 1.135 inches. I plunked 10 rounds and 5 out of the 10 rounds did not plunk. 3 of the 10 rounds were sticking up well past the end of the chamber. I had just cleaned my barrel, so there was no dirt in the chamber preventing the rounds from plunking. Needless to say I was disappointed and will not be shooting these out of my Accushadow 2.
