    CZ P-01 trigger weight reduction modification

    Mods: Please move to appropriate section if needed.

    My first post and new gun owner so please go easy on me.

    I picked up a P-01 after not being to find SP-01 anywhere (few weeks back). This is not a carry gun, it's mostly a range gun. (SP-01 is probably a better choice, CGW one was bit out of my budget).

    Love the gun overall but I feel It could use some polishing and a for my taste a lighter trigger pull system. As it sits at stock, both DA and SA are a bit much. I don't want to go crazy on the modifications and drop that much money into this gun. It's a holdover until I can find and buy possibly a CGW SP-01 Pro (once I have the extra $, to me this is more of a hobby so $ is a concern)

    Goal: Reduction in trigger pull WEIGHT. travel reduction would be plus but not Critical.

    Option 1: https://cajungunworks.com/product/54420-ultra-lite/ a little confused on the description. "Cuts the DA an amazing 50% with our HS-13 “blue” music wire hammer spring and still delivers 100% reliable ignition." Cut's 50% what? I intend to use the Blue spring with any of my options but what exactly is it cutting? Trigger pull weight (as is my goal of doing the mod). Obviously the lighter spring, longer firing pin point to a lighter hammer which in turn should me lighter pull of trigger. Just needing confirmation on this.

    Option 2: https://cajungunworks.com/product/sr...-reset-system/ in this for $22 more you get the Short arm lifter, everything else is basically what's in option 1. Is the short arm lifter required for SRS to be effective? what do I gain from having this over option 1? what is the benefit of it over OEM lifter? is it's purpose only a shorter reset?

    Option 3: https://cajungunworks.com/product/75...ries-decocker/ going a slightly bit further (a bit more than i want to put into this gun) and getting this kit that includes a Race hammer. How does a Race hammer vs Stock hammer effect the gun with above 2 options? Since i'm not changing the sear nor the cage or anything, how does just the race hammer change things?

    I'm sorry about the noobish questions. just trying to wrap my mind around all the different packages which seems to be just an addition of one or two mods from the previous combo package (example the Pro is same as the defense package except the addition of short reach trigger system)



    BTW, i'm capable to doing all these modification and update my self. so I'm not worried about that.


    PRIMARY QUESTION: With option 1, a good polish, will I be able to reach weight reduction and smoothness of the trigger in SA and DA ?

    SECONDARY QUESTION: Can I also lower the recoil spring weight? since the Hammer spring is being changed? The stock slide is bit hard to pull, It's slipped out of my grip a few times while pulling back, poor guy who was helping me at range got a nasty finger pinch and cut because it slipped out (he was used to CGW Pro SP-01. I'm sure polishing will help but what about the spring?

    Seem to be good questions to me. I too have a p01 and am overwhelmed by the options on cgw website. But oh man how I dislike the unpredictable travel and break of the stock trigger.

      that's why I want to polish up the gun and do the Short reset update to clean up the trigger pull.

      As much as I like the gun, I am a bit disappointed at the tooling and lack of any effort to clean it up. I run my nail along the bottom of the slide rail and it feels like those little bumps on side of the freeway.

      I'm reading up on best polishing options without taking any metal off but with tooling marks this deep, I don't know what to do.

        Welcome to Calguns, and congrats on the P01! CZ pistols are awesome. Warning, you won't have just one for very long.

        I would recommend getting the following for your P01:

        - ultralite self defense kit the springs will greatly lighten the pull of the double action
        - CGW Hammer A good hammer will lighten, smooth out, and give a crisp single action pull
        - tapered punch and slave pin (helps tremendously when you have to remove the decocker cage. The slave pin will keep it as one unit)

        All of this will run you about $150

        I did the same thing to a SP01 tactical, and it's a nice trigger pull. I didn't do any polishing, so the DA isn't as smooth as it could be. However, when you put in those springs that lighten the pull of the DA, it is definitely better. Even with no polishing the difference is night and day with just these two upgrades.

        As you said, since you're just trying to be held over until you can get an SP01, I would recommend getting the 3 piece spring kit and one of the CGW hammers. Those two things alone will hold you over nicely. Once you get an SP01, then you can go crazy on a trigger job.

        Also, I'm not sure of your experience working on handguns, but the decocker CZ model is one of the more complicated to work on. I'm not saying you're unable, just beware if you plan to get into that decocker, such as changing out the arm lifter, if you go that route.

        There are a few guys on here who have a ton of experience with CZs. There are also some good write-ups and videos on doing these exact modifications on the web. They greatly helped me.

          from my understanding.

          option 1 and 2 reduce DA pull and pretravel. I have option 1 with the reduced trigger spring and its great.

          adding the hammer mod will reduce SA pull/break

              I'll try to answer your question as directly as possible. The blue spring will cut the pull weight of the DA pull. The SRS kit will reduce the travel of the trigger forward before it resets for the next shot. The race hammer has a different cut on it and will provide a cleaner and more crisp brake in SA. I'm a lover the cz line but if they messed up one thing one their guns it's the gross SA break with that stock hammer.

              If your goal is to make it a better overall range gun, I would suggest some reduced power springs and the hammer with adjustable sear.

              Keep in mind if you reduce the pull weight of the trigger that any sloppiness in the trigger break will become more noticeable. You'll want a cleaner, crisper break the lighter you make the trigger pull.

                Welcome to Calguns OP!

                Kjv146 has some good suggestions for your range gun. There are some other very knowledgeable CZ users here who will likely chime in soon as well.

                My P-01 actually came with a pretty good stock trigger (lucky I guess). I may add it to my CCW when I renew, so I don't want to do any mods at all. If you ever plan to CCW yours, then you may want to re-think the mods. If you do the mods, they should definitely improve your range experience.

                Enjoy!

                  I'm not up to date on CGW offerings, when I did mine he still was recutting factory hammers.

                  I will say though, it is worth taking the extra time and cleaning up the trigger bar. It may mildly reduce DA weight, more likely just smooth it out.

                  Single action is all due to the hammer hook angles, which CZ factory has some extra camming which you won't "shoot" out. Springs don't really effect the SA pull either.

                    Thanks everyone for all your replies and suggestions. It's all starting to make a bit more sense now on what purpose each price and mod performs.

                    The hammer mod didn't make sense to me at first, but after reading up on hammer camming and going back to my p-01 and seeing it first hand, I can see how SA can be much improved with the modded hammer.

                    KJV, along with your recommendations, would a type 2 disconnector help as well with the SA?

                    Because now I'm thinking I might as well get the Option 3 with type 2 disconnect included as well.

                    Considering my gun will shoot 9/10 bullets at the least in SA mode, it's best I work on the SA as well as my DA.

                    Ahhh choices and money.

                      I chose NOT to do the hammer. I have the hammer in my SP-01 as a SAO gun and it is lovely. But I wanted to see what I could get away with on the P-01 without the hammer. Did pretty much what you are considering without the hammer and I'm at 6.1lb DA and 2.3lb SA.

                        The type 2 requires the SRS Kit.


                        Personally, I would start with a hammer and spring upgrade, and go from there. I'm not a "reset" junky though.|

                        Take a peak in here in some ways to clean up the trigger bar areas that interact with the disconnector.

                          Anyone know a person that can work on CZ triggers in San Diego? I don't want to spend like $300 for the fancier upgrades or lose some parts while taking my gun apart down to that level. Thanks.

                              Thanks for the help Par5In2!! You are so correct with just the few needed parts without spending $300.
