So I got my CZ 97B and I really like it. But of course one can’t leave good enough alone.
Obviously the primary upgrade I have in mind is trigger pull. Please let me know where to look for appropriate upgrades.
I want to reduce both DA and SA but would like it to remain safe for carry with loaded chamber/ hammer down. That way safety can be off and first round fired will be heavier DA.
Seems to work fine for my P228 and 229.
Suggestions and opinions are greatly appreciated.
Any other upgrades I should consider for the 97? Grips? Extended mags?
-
Cajun Gun Works Pro Package is most likely what you're looking for. The kit will keep your 97 DA/SA while improving the trigger pull in each mode. Just my personal opinion. Good luck.
-
CZ custom also offers an excellent package.
-
Would there be a preference between CGW or CZ Customs?
-
I've ordered parts from both companies. As far as trigger upgrades go, I've only ordered from Cajun Gun Works. They are both very good companies to deal with. You can't go wrong with either company. Are you planning to upgrade the trigger yourself?
-
Thanks for the reply. I will check out each companies offerings. Yes I will install myself. Not a concern.
-
Wow!! Over 300 for the upgrade kit. I’ll have to pass for a while after just paying for the gun. Still looking for a decent holster though. Not sure I should even try for IWB due to size of the gun. Any one EDC the 97? Thoughts?
Any more suggestions on holsters?
How does the guns finish hold up to a Kydex or leather holster? How quickly does it wear off?
-
For reduce DA/SA trigger pull, 13# Hammer Spring ($7), Extended Firing Pin with Spring ($25), and Firing Pin Retaining Pin ($5).
I kept the original Firing Pin Block Plunger Spring on my P-01 (carry) and have the lighter spring on the SP-01. This is for 9MM 75 but found similar items when looking at 97B upgrades as well.

So the items you listed will fit in the 97 without changing anything else?
My main concern is exactly what you mentioned. Reducing both trigger pulls while keeping it safe for carry if needed.
Concerning safe carry, what would be an acceptable safe carry condition. Only options I see would be the obvious loaded chamber, hammer down for DA first round shot. I usually carry my 1911 in condition one, hammer cocked and safety on. But this isn’t a 1911 and the manual safety is NOT very positive. I’d be afraid the safety could be accidentally turned off while carrying.
Any thoughts or experiences?
Is it safe to carry hammer down on loaded chamber or is half cock necessary?
-
My preferred carry method for my CZs is loaded and de-cocked (half-cock or quarter-cock). Not sure of the exact technical term. All my CZs have de-cockers on them, but I would be comfortable to carry one hammer cocked/safety on. I used to carry 1911s - condition 1 and carry loaded glocks in the past.
The opinions above are my own and others might have different take and I respect those as well.
-
I carry my 97B cocked and locked IWB in either a Vedder Light Tuck or a TTGunleather Slim XC. Never had a problem with the safety being bumped off. Both holsters have sweat shields, so the safety lever is covered. I also, on occasion, carry it in a M7 shoulder holster. Check out the sticky at the top of this forum for other holster options.
Note: I use Perry suspenders all the time, no matter what I'm carrying, from my 97B down to my CSX. Nice not having to cinch up my belt!

So it depends on your intended benefit. The CGW extended firing pin for the 97B/97BD along with a lower main spring will reduce the trigger pull without changing anything else. It is a solid budget friendly choice. The 97B firing pin is not the same as the 75B variants. Make sure you get 97B specific parts.
To go any further, you should just purchase the Pro Package from CGW. It is a simple solution that will transform your 97B trigger. I should caution, once you start modifying the CZ action you will be ruined and all your CZ's will need to be reworked.
How to carry the firearm is a personal preference. It is completely safe to carry locked and cocked, hammer decocked, and hammer down fully. It has a firing pin block mechanism that should prevent discharge without pulling the trigger. Personally, I'd carry it decocked but I'm not sure I would want to carry a 97BD (concealed or not).

Many helpful comments here. Thank you. I will most likely do the simple trigger upgrade mentioned. Maybe to full kit later.
Still researching the holster options.
I feel better about safely carrying in either condition. Thank you.
I’m actually headed to the range now to shoot both the 97B and my 1911 side by side. Just to see the difference in accuracy. The 1911 is in 460 Rowland configuration but still shoots 45 acp just fine.

For reduce DA/SA trigger pull, 13# Hammer Spring ($7), Extended Firing Pin with Spring ($25), and Firing Pin Retaining Pin ($5).
Along with the listed items above, could the CGW replacement hammer be added without changing anything else for a crisper pull? Or does it require the full kit?

You'd be better off ordering the adjustable sear as well. The CGW hammer advances the timing and either the sear will need to be modified to fit under the safety knob, the safety knob fitted to the sear, or an adjustable sear is purchased/installed. The adjustable sear is the easiest option. If you take too much material off trying to fit the parts then the safety operation could be compromised and you'll be purchasing parts to restore operation.
But yes the competition hammer can be installed stand alone and it will eliminate the majority of creep in the pull. It will also lower the SA trigger pull noticeably.

If you want to change the reset and trigger "slop" you will have to add a trigger with adjustment screws, a short reset lifter, L spring, and a disconnector.
You are essentially going to have the pro package built at this point. Hence the reason for the original suggestion to just go ahead and do the pro package.
If you just want to eliminate over travel then an original 85C trigger with pre and over travel set screws is needed. A floating trigger pin is also very helpful for ease of reassembly and future tear downs. I'd also suggest a hammer pin for installing the new hammer.
Look at the contents of the pro package and decide. Better yet, call CGW and discuss what you want and they will ensure you get what you need. They are very helpful and willing to spend the time over the phone to help answer questions.
Cheers,
Toby
-
Thank you Toby. I will give them a call.
-
Wow!!
I placed the order for the 97B Pro Package yesterday around noon. Package is OUT FOR DELIVERY right now. Should be arriving any minute. Just WOW!
I already have my gun completely disassembled and ready. Although, I need desperate cleaning from range session the other day.
I forgot to weigh the standard DA/ SA pull weights before pulling it apart. Can someone let me know what they are for my records please?
Thanks.
-
My stock 97BD had the following average trigger pulls:
SA: 3.5 lb
DA: 10.5 lb
It varies a little with age and use as they break in and smooth out over time.
With the Pro Package I'm going to guess you are going to be the following:
SA 2.5 lb
DA 8.0 lb
Congrats on the addiction! You will be spoiled with a tuned CZ trigger. Good luck on the install!
Cheers,
Toby

CZ custom also offers an excellent package.
+1 And they’ve been doing this long before CGW came on the scene. Truth is, neither company would exist if it wasn’t for CZ’s crappy triggers.
-
In the 97b pro package I received, there was not a reduced power trigger safety plunger spring, as well as an extra power plunger spring. What is the difference? Which do I use? Instructions are not very clear.
-
You can use the plunger spring to tune the sa pull weight. I'd start with the light one and see how it feels

Enjoy tuning your pistola.
-
Thanks. I’m sure I will enjoy it…once I get done processing this deer meat. 😁
-
Stupid question. Is the Red Loctite they say to put on the various screws in the Pro package the PERMANENT kind? For some reason using that stuff worries me.
-
I'd red loctite the adjustable sear.
You can get away with blue on the trigger set screws. Red works as well.
Red isn't that hard to loosen with heat.

CGW recommends the use of red on the adjustable sear since once it's set and the safety is operating properly there is never any reason for further adjustment.
-
Ok. Got it. I got some red.
-
Pro package installation complete. I think I did it right. I do have one issue that bothers me.
When I pull trigger, the then wrack the slide while holding trigger rearward, then slowly release, I get a very quick and light reset but as I continue to release the trigger there is another audible “reset.” To I get two clicks when releasing trigger for SA reset. What did I do wrong?
-
Check the trigger bar spring tension.

I will certainly check this out asap. Certainly sounds exactly like my issue. A “false” second reset.
One other issue I’m noticing is my safety will engage with hammer down. I’ve adjust sear screw to just touching the safety as directed.
-
My trigger pull weights are
DA - 6 Lbs 4.5 oz.
SA - 2 Lbs 11 oz.
May install heavy plunger spring to increase those a little.

With the adjustable sear you will be able to engage the safety with the hammer down. This is not a safe condition to carry and you shouldn't do it ever. If you pull the trigger with the hammer down and safety engaged, you can damage the action and it most likely will fire.
It has to do with the sear set screw not having as much surface area to cover/interfere with the safety nub to prevent actuation when the hammer is down.
Otherwise with the hammer cocked the safety should prevent firing as intended and designed.

Well that’s not good. I thought the sear set screw was to correct that situation caused by the new hammer so it WOULDN'T allow safety to be engaged with hammer down. Hmmm 🤔
So with the pro package installed, what you’re saying is it’s not safe to carry the weapon?
-
Might be the wrong sequence for this to happen, but maybe the sear is contacting the hammer hook. Double check that the over travel screw on the trigger is set correctly.

No, with the stock parts you can't engage the safety with the hammer fully down. It is safe to carry the weapon with the hammer down/half cock with the safety off. You can also safely carry it hammer fully cocked and safety engaged as well. It is just a new condition that you can now engage the safety with the hammer down but that isn't "safe" and shouldn't be done due to potential damage to action parts. Since the firearm is a DA/SA gun it will fire with the hammer down or with the hammer cocked. The safety doesn't prevent the DA hammer from cocking the hammer (hence the reason you can't apply the safety with the hammer down with the stock parts).
The adjustable sear is designed to ease the fitting process. Otherwise you would have pull apart the sear and fit the safety leg, reassemble and test. That iterative process would repeat until you are able to engage the safety and if you took too much off would require a new sear.
Here are the instructions from CGW that outline the adjustable sear differences: https://cajungunworks.com/installation-instructions/manual-safety-hammer-installation-instructions/

My friend, who has a Cz97 with stock parts, says my new light weight CGW trigger is not safe for self defence carry. Not that I’d try to conceal carry this big beast. I really only see this being a range or wood outside belt carry gun.

Your friend obviously knows his own limitations and should operate within those parameters. That said your 97 is perfectly safe for defensive purposes although again that is your choice. I have the full package in my 97's and I have no problem putting them in a defensive role.

I appreciate the vote of confidence. I like lighter quicker triggers.

Welcome to the CGW addicts! As far as I know there is not CGW Anonymous meeting so no worries. I geeked up and bought the Wheeler digital trigger gauge since it lets you press directly on the sensor which is in turn directly on the trigger. My 97B has an average (30 trials) of 6.5# DA and 2.3# SA. With the short reset it runs like mad and is still safe for EDC. I don't wear suspenders so it's my fun gun rather than EDC.
Enjoy your weapon!

I've carried the 97 in shoulder holster numerous occasions. love the all steel.
Congrats on the fine pistol
