CGW #11.5 mainspring in a CZ75B

[Long Branch Setter]

I have a 75B that’s been upgraded with a CGW Short Reset Kit. At the moment the #13 Lb mainspring is installed with no problems. I’d like to put the #11.5 Lb. mainspring in to get the DA trigger pull down a bit more. Anybody shooting a gun with the SRS and # 11.5 lb mainspring? If so, have you had occurrences of lite primer strikes?

Thanks in advance for any input.

Are you using an extended firing pin?

Are you using an extended firing pin?

Yes. CGW SRS with extended FP and reduced power FP spring.

It may depend on the ammo and the specific pistol but generally i think you are good to go. With the Extended FP and Reduced Power FP Spring installed it seams to be the 8# Hammer Spring or folks running the 11.5 or 13 in the Kadet Kits that that have issues.

While i shoot only a limited variety of ammo i have not had any issues with the 11.5# Hammer Spring in my CZ75 variants. I can not say that i have heard any one els have issues with the set up but i do not keep a real close track of the subject.

I think you should be OK.
If my #13 spring works with factory firing pin, my guess is that #11.5 spring works with extended FP and reduced FP spring.

but:
I don't shoot reloaded ammo, only Fiocchi, S&B and CCI Blazer.

I run 11.5 lb main springs in my Shadows.  Also have the CGW extended firing pin and reduced FP spring installed.  Ignites CCI and S&B primers no problems.

^^^  Ditto for my 75B and two SP-01's.  11.5# spring with extended FP.  Never had a problem in any of these.

I have had a 15 lb hammer spring and factory internals in my 75B for a few hundred  rounds now. No misfires 9r malfunctions with that setup, but the dimples left in the spent primers are not as deep as I'd like them to be.

Srs and 11.5# spring in my ms 75. No problems what so ever. No light strikes in ~600 rounds
