cnote Posted July 19, 2010 Share Posted July 19, 2010 what is the purpose of czcustom's (Angus's) CZ 75 Extra Power Firing Pin Spring extra power would hinder/slow the pin? I could see the extra power extractor spring making that function more reliable, but the other confuses me thanks, Mike Link to comment Share on other sites More sharing options...
J-Hon Posted July 19, 2010 Share Posted July 19, 2010 Useful when you are trying to work your DA pull weight down by lowering the mainspring weight. IME, 13lb is about the limit to set off factory ammo, and I'd feel more comfortable running 15lb springs if running stock FP/FP springs. I run a longer firing pin, and the extra strength spring with a cut 13lb mainspring. It works. Link to comment Share on other sites More sharing options...

JimmyZip Posted July 21, 2010 Share Posted July 21, 2010 I don't know for sure, but with the XL pin, this might keep the extra mass of that pin more stationary until the hammer drops to prevent a slam fire? Link to comment Share on other sites More sharing options...
