I've had a trigger job from Angus at Ghost Industries. Is there any advantage to changing recoil spring to 14# or 16# on my CZ 75 B ?

Drop Angus an email and ask what he recommends.

well the stock spring in the CZ 75b is a 14lb recoil spring, I would see no advantage of going to a 16lb spring unless you plan on shooting a lot of +p ammo. A lot of people go the other way for different reasons as it changes felt recoil and you can run lighter loads.

Advantage of keeping your brass close by if you reload;)

I went through a phase were I though I had to increase the power of my recoil springs in just about every pistol. The problem is that it can have an effect on operation, feeding, etc. I also increased the mag spring weights to counter the higher power recoil springs. Most of my guns functioned OK, but I have since switched most of them back to factory standard weight recoil springs. I don't shoot +p in my pistols, but I do carry it, so will check it for function only.

I would keep the 14lb spring, but if you feel it is undersprung, get a Browning Hi Power spring from Wolfe.

A stronger recoil spring (depending on its strength) can be harmful. Recoil springs don't do much to "protect" the gun as the slide goes back, but do cause the slide to slam forward with extra force as the slide returns to battery.

If you're having to chase brass, and you reload, a stronger recoil spring may be useful -- otherwise, the 14 lb spring (or even less) will work fine in a standard (full size) 9mm CZ.

As others have suggested, however, check with Angus or someone at his shop. He's forgotten more about CZ than most of us will ever know, and still knows more than we do.

(Note: the BHP springs from Wolff are closer to factory CZ springs than are the Wolff springs for the CZ [which are REALLY for the Witness line, and have a larger coil diameter]. The BHP springs are physically the same as the factorey CZ springs, if you get the same weight. The standard BHP spring, however, is 18 lb., and you'll have to get one of the lighter Wolff BHP springs when using one in the CZ; last time I looked, their lightest spring for the BHP was 14 lbs. They do offer a variable rate spring 14 lb. spring, which I'll get the next time I need one.)

If you just have to do so, I recommend replacing the slide stop at regular intervals (e.g. every 7500 rounds) if the weapon has any place in your personal defense plans.

You all have convinced me. !4 # appears to be best choice. In a conversation previously with Angus - he uses 14# for the most part - depends what he's shooting. I'm just basically punching paper with normal loads.

Thanks for all your input, buddhas
