New CZ75B
« on: September 29, 2018, 10:32:16 PM »
8.14# da
4.13# SA

STOCK

not that bad trigger pulls.

Anyone else typically see pull weight like this stock?

It's nice but could use some work. Would like to reduce reset and lighten up the weights a bit to make it a good production gun for uspsa.

Torn between doing cgw pro kit myself, send it, or have a local Smith install it.

Can anyone help me with some options.

In my experience your listed trigger weights are within normal range for a factory stock CZ 75 variant pistol. I would suggest reviewing some of the available CZ safety model tuning guides to help decide whether or not you want to DIY.

Here are a few good ones.

Thanks

I saw that his trigger weights were above mine which is why I asked for confirmation of trigger pull weights stock.

Taking everything a part doesn't seem like the hard part.

Putting it back together does.

CZ safety models really loose allot of their mystery once you get them apart. While i believe that most anyone can work one them, preparation and thoroughly reading the guides can be a key factor in how smooth the process goes. If you like to tinker that is also an asset. Keep in mind that each CZ is unique to the next, some you can just drop the parts into, while others require special attention to achieve the same level of refinement. For clarity my point is that if you are not content with the outcome of your DIY work you still have the option of sending the pistol out for more professional work.

Working on a CZ can be allot of fun if you approach it with the right mental attitude and patience.

You mentioned competition, that is outside of my area of experience. Due to the specific rules on modifications i generally do not make suggestions on the subject. Thankfully there are many other forum members here that have significant experience in that realm. I look forward to hearing their suggestions.

Is it bad I wish it was as easy as dropping in an AR trigger?

I mean I can work/build an AR. But I don't do well with little pieces of metal lol!

And that whole patience thing lol. Ehhhhh

I hear you, i did not approach CZ gunsmthing in an advantageous mindset at first. I forced a number of things, lost my patience and learned some valuable lessons in the process. I would suggest not building thing up in your mind until after you have spent some time reviewing the guides and videos on the subject. They can really add allot of facts in place of speculation. Safely models are really just pins and springs. Now pins and springs can certainly give you trouble in the right combinations but then trouble can be fun depending on how you look at it.  ;D

I have a shadow 2 that I shoot at USPSA Production. I had modified and polished the internals and got the DA to 5# 3.4 ozs, SA 1# 9.9 ozs. I bought the parts parts Cajun and installed them myself. It?s easy.

You can find tutorials from YouTube. Just take your time when you?re doing it. I also use professor Atlas? polishing tutorial in polishing the internals of my shadow 2.

Here are the parts I bought and installed from Cajun gun works.
11# hammer spring
Reduced power firing pin spring
Extended firing pin
Floating trigger pin
Reduced power trigger pin spring
T3 disconnector

Nice. With that shadow 2 you didn't need the 85 trigger.

Which I understand

Any reason why you just did springs and disconnect and not the hammer?

When you polished, did you use 1000 grit sand paper by hand?

Tok36 has given you good advice.

I would only add that the 75's mechanism includes many small parts, but is relatively easy to work on with the proper tools **. The mechanism that gives beginners fits is the decocker version, which yours is not.

However, before any work commences, it would be to your great advantage to go shoot 800-2000 rounds, with cleaning and re-lube after each range trip. CZs always improve with use. Thereafter, you can improve the gun in stages, starting with simple things like the reduced hammer spring.


** Most novices that want to work on guns do so becasue they already have a collection of tools for car and home repair. These tools are WAY too big. Gun parts by comparison are 100X smaller. So besides the Chapman screwdriver set, you're going to need a magnifying headset, tweezers and lots of cups to place small parts in.

Moebravo-
 I don't speak for George, but I've pulled the trigger on a few S2's and on some the trigger is quite nice with a clean break. Sometimes all they need are lighter springs and a short reset disco.

This has also been my experience with non-decocker, thumb-safety CZ's, like the 75B and the 75 Compact.  The trigger pull improves significantly with repeated use.

I actually modified my trigger. I bought an old style 85C trigger from Cajun. Heated it on my gas stove and straightened it out a bit to feel like my TSO trigger.

As for polishing, I used 1000 and 1500 grit sandpaper strips I bought from an auto parts store. Final polishing was done with my Dremel using felt and mag polish.
