My P-01 and the CGW blue 13# hammer spring
« on: February 29, 2020, 01:01:56 PM »
Hello all, (fair warning, looong post with questions!)

I've been reading these forums for about a couple of months ever since I bought my CZ 75 P-01 when I came across this Site as an avid Internet researcher whenever I buy a new toy and tend to totally geek out on it! Thank you for the wealth of information and my apologies if this issue has been dealt with before and if I cut the line without delving more into the stacks of reading material in here already.

When I had originally decided on a CZ P-01, the only negative factor which I saw on various online comments and feedback was this "trigger slap" issue; admittedly not too many but in general the gripes about the "lower end" CZ 75 variants seemed to have been regarding their triggers. There was a here somewhere which I had read folks asking what is the first thing to do when one buys a new 75 model and most owners had opined about getting and installing the CGW's Old Style Trigger (for the 85 models?) incarnate version plus the floating pin and the reduced power trigger return sprint. So I ordered a few stuff from CGW including the mentioned items (the other items were just an extra mag and accessories not related to performance for this discussion). Then I read some more and I took it upon myself to call the friendly folks at CGW to see what else they would recommend to a complete CZ rookie like me (I'm an old school Beretta guy) and the gentleman who I spoke with recommended 54420 Ultra-Lite Kit and for good measure I also went ahead and added a SS guide rod to my order :)

Now a bit of background: I'm in the state of CA (San Diego) and with all the extra hoops we have to jump through in here, sending my new handgun out to CGW for a complete Pro-Kit conversion after a long wait period to be added to another half dozen to dozen weeks at CGW was not a great option for me so I decided to do some minimum recommended stuff to see how it goes before I embarked on something more substantial later on, perhaps with a second 75 version. I discussed what I wanted to do with my gunshop and they told me that the trigger job was a bit tricky for their resident smith so they had to have their part-time smith to pick up and work on it (reported a very capable smith who apparently does outside work for a few gunshops in here). If you have made it so far, thank you for bearing with me ;)

The trigger did give this smith a bit of a hard time but he managed it. He called me and told me that for the hammer springs, the black one felt a lot better to him so that's the one which he installed, told me to handle, dry-fire, live-fire and see how I feel about it. When I picked up the gun, the trigger action was smooooth and in fact scary light and true to form and to CGW's description, it really felt like about half as much or even less pulling pressure and like I had said, SCARY LIGHT! That said, a bulb went on inside of my head and I went back to re-read the description and there it was: "the blue 13# for defensive and the black HS-12000 for range and competition with the former being deemed as reliable for igniting all primers". I even emailed CGW and in their response they stated that the blue 13# was in fact "mandatory" for defensive purposes (word they had used in response). So I took the P-01 back and they replaced it at the shop within a fast few minutes. I could've done this myself but just wanted it to be handled like I had commissioned it.

Now the DA, at least to me, is about how it was or thereabouts originally with the CZ factory set up! I honestly do not feel 50% reduction or anywhere near what I felt with the black CGW hammer spring. I know that my mind could be playing tricks on me, but without using numbers and percentages that could be open to disputes (I don't own a pull gauge) I know that the difference is how it felt and does now is quite significant. As far as the SA goes, there is a little bit of creep and then one very small almost gritty phase of the creep before it hits the wall. I don't know if it's the spring (they are cheap and I can order another), something went wrong during installation or what else? I will not be switching to the black HDS-12000 because this is not intended for range only and I do not compete either.

Final thoughts: I have ran through the possibilities that yeah, I may have half-arsed it by not sending to CGW but wanted to explore the other possibilities. It is also feasible that the "grit" which I had described was always there and it's something with the trigger but I just did not notice because how light the HS-12000 was, I really do not know but thought that the much more experienced folks can possibly shine more light. Also in closing, this post is not intended as a criticism of CZ because as a CZ convert, I'm already getting the RAMI 2075 as my subcompact :)

Hoping that the TL; DR version of the above "essay" produces some responses. Based on ad hoc online research as a complete newbie & noob, I came across this site when looking for some basic upgrades for my recently acquired P-01. Here's what was ordered from CGW and replaced so far by a local smith:

- Old style trigger (SS)
- Reduced power trigger return spring
- Floating trigger pin
- Ultra-Lite kit (54420)
- SS guide rod

Firstly the HS-12000 was installed but per CGW, that was replaced by the HS-13. The issue is that the DA feel differential is now quite substantial as opposed to the claimed 60% vs the 50% respectively as compared to the OE. Further, it feels like that the SA has also become a bit gritty just after the creep and hitting the wall.

I have started reading the entire CGW sub-forum from the beginning to learn more but would greatly appreciate some insight as to what I could've done wrong or what else would be recommended, i.e, adjusting the trigger over-travel or else. Upgrading to a full pro kit and sending it out to CGW for the full R&R, is not an option at this point :(

Thank you :)

   I suggest putting 500-1000 rounds through the pistol. The action should smooth out significantly after it is well broken in. This applies to both the Single Action and the Double Action pulls. While this will not reduce the DA pull weight by much, it will smooth it out. A smoother DA can feel lighter than a rougher DA even at the same weight. This applies even to the in house full CGW Pro Package CZs. There is no replacement for fully breaking in a CZ 75 variant pistol in my experience.

   Some of the changes in the trigger that you describe do not correlate with a hammer spring weight change alone. It is possible that some of this will be shed during break in. There is only one way to be sure. 

Thank you for the pic. Gratz on your new CZ, may it run flawlessly.
Will work for CZ pics! (including but not limited to all CZ clones)

Thank you very much for your input and yes, I will definitely do so.

I went ahead and ordered another 13# hammer spring plus a 16# factory compact recoil spring which seems to be an often very fast selling and out of stock item. having a few inexpensive extra spare parts never hurt anyone ;)

Also looking forward to picking up my RAMI 2075 next week (CA BGC procedure). I will most likely leave that one completely stock just to see as to how that one will smooth out after 500-1000 target practice rounds.

Again, thanks for a welcoming platform for this new CZ fan.

I'm with you, at least as it pertains to the 13# hammer spring.  I just installed CGW's 3-spring kit in both my P01 and P06.  I can't really feel the difference either, certainly not a 50% reduction in DA pull.  I'll be interested to see how your next spring feels.

Casino,
I recently purchased a PO1 and essentially did the same thing.  The 85 trigger (I hate the extreme curve in the stock trigger) floating pin, extended firing pin, reduced firing pin spring and I installed each of the hammer springs and settled for the 13 lb to insure I got reliable ignition.  Did all the work myself and I am pleased with the results.  I also installed the TruGol TFX pro sight set.  I have this set of sights on my Phantom also.  Really like these sights.  I really like CZ products.  Both the Phantom and the PO1 shoot well.  Only issue I have is the PO1 seems to shoot low in relation to the POA compared to the Phantom.  Not low enough to give me worry and I've really not shot it enough to figure it out.

Enjoy yours.

Ironhand & Houstonxd40: thank you both for your input. My apologies for my very long and tedious OP but as I had stated somewhere in there, the HS-12000 was scary light which per David @ CGW, it had to be replaced with the blue 13# as a "mandatory" no-choice OE replacement for anything deemed as defensively purposed.

As for sights, I went with Meprolite tritium true-dot which I pick up a lot faster and easier than the OE sights. So yup apart from the CGW bits and pieces, I have added the sights, the LOK grips (but may still look for a set of OE aluminums when I get bored with the LOK) and the OLight Mini-2 weapon light as shown.

As mentioned in my other post, I will just rather stay all OE with my RAMI, partially because I have spent far too much $ recently on some toys and partially because I want to see how the all OE RAMI will do against a slightly mod'ed P-01. The trigger on the RAMI juts did not feel as adversely as the OE tigger of the P-01 did, well, to me anyway. I can also live with the OE grips on that RAMI because of the none palm-swell and also that the RAMI's rubber grips didn't feel as tacky as the OE P-01. As a side note, here in CA because of the restrictions we have on our gun laws, some of these other wonderful CZs which some of you may own, are not available for sale to us but I think that I can and in fact, I may consider a full size SP-01 at some later point :)

You need to get to Home Depot or a similar store and purchase some O rings. I don't remember the size you need but a quick search here should give you that info or one of the others will chime in. You put the O ring between the firing pin and the hammer and then you can sit and dry fire as much as you like. The more you do this the better the feel will get. Enjoy the gun.

Did a quick search and this is what you want.

You can also cut a foam ear plug in half and place it between the pin and trigger.

Nice gun, like the green. I installed the CGW 75700 kit in mine, for carry I wanted the pull around 4.5-5 lbs so I left the factory trigger return spring in but replaced all other springs issued in the kit. Trigger pull is now 5 lbs, no creep whatsoever. I don't want a light pull (say anything under 4) weight on my carry guns. I guess if you practice with a light trigger enough it would be fine for carry, but I feel better with a little heavier pull.

rkwhyte2: thanks a lot for your input. I've actually gone the snap cap route (A-Zoom brand) with all my guns when I dry fire and practice simple drills with them, but yeah, when I was just reading up before I joined the Site, I did note that some folks use those O-rings :)

NMShooter: thank you for the kind compliment. I totally understand where you are coming from regarding your preferences on your carry gun. I have forgotten as to what the original P-01 DA resistance was, maybe 12# or slightly more? But I very much doubt that the blue spring has reduced that resistance by anywhere close to 50%. It has most definitely reduced it alright, but not by that much as claimed. When I had the HS-12000, yes definitely much much lighter, so much so, that it scared me!

ETA: I think that you are talking about SA trigger pull which is where I am experiencing that creep and the slight grit before the hammer drops. FYI, when I hit that phase which I call the "grit", I do see that hammer move before it drops. I don't see that very minute movement when the trigger creeps before it grits.

For now, this P-01 will be a home defense in addition to range handgun. I do not have a CCW permit here where I live in Cali but I do have another state's CCW for when I am traveling by car outside of CA (reciprocal in 30+ other states). The RAMI should lend itself better for that purpose plus being a subcompact on person carry.

I read your entire post and this is what I came away with. ^^^^^^^^^^^^^^^^^^^^^^^
 
When a gunsmith says it's tricky, one doesn't double down, one simply walks away.
Have you thought about working on it yourself? It really isn't that hard and gives you the opportunity to learn your pistol inside and out.

Very fair point Chuck James. BTW, thank you for reading that entire OP. I am not well adept at that task right now, but I am reading posts, absorbing info and watching some videos to feel confident enough to mess around with the trigger and the firing pin. You are right for highlighting that sentence in my original post's last paragraph ;)
