CZ 75B- trigger pulling weight improvement ?

[newbie1234]

I had CZ 75B and 75BDCompact, how can I improve the trigger pulling weight ?
I just want something DIY, do not recommend me to disassemble the whole pistol and polish every part - it's too difficult , nor send to CGW - it's too easy

Best Regards.

First, spend less time on calgun, second go shoot your cz bd. This will smooth out the rough edges.

There's a couple web sites that can help you out, here's one:

On my SP01 I loaded up some snaps and went to town while sitting on the couch. 50 pulls with one hand and when I got tired switched to the other. 2 nights of doing that and the trigger felt much better. Still heavy but smooth.

I was gonna say, change to lighter hammer spring and extended firing pin.
But since that involves some disasembling the pistol, just shoot it, or dry fire with snap cap will smooth it.
Or you can sell it to me for cheap, I'll take that thing apart and put it back together with the CGW upgrades LOL

OP i believe a lighter hammer spring is your best option. Changing a hammer spring requires limited disassembly. Just remove your grips and push out the main spring plug retaining pin. As a rule of thumb a hammer spring will effect the DA by pounds and the SA by ounces. I believe that with the factory firing pin a 15# hammer spring is the lowest you can run without the potential for light strikes.

While you are at it you may want to consider a lighter recoil spring. CZs tend to come sprung heavy from the factory. I like the CGW tuners kit, it comes with a full range of recoil springs to experiment with.

I've installed this kit on a P-01 and on a SP-01

You'll need a hammer, punch and I suggest a bar clamp with rubber tips to act as a 3rd hand when changing the mainspring. It's a pretty easy upgrade.
I used the "blue" main spring to assure 100% ignition.

On the SP-01

DA was 12 lb, dropped to 7 lb 11 oz
SA was 5 lb 12 oz, dropped to 4 lb 11.6 oz

On the P-01

DA was 10 lb 3 oz, dropped to 8lb 1oz
SA was 5 lb 5 oz, dropped to 4lb 8oz
