extended firing pins and stock hammer springs reinstalled
« on: May 01, 2021, 08:54:20 AM »
own a sp-01 and a p-01 and both have the extended firing pins with 13 lb hammer springs. i know you can go very light with hammer springs with the extended firing pins installed but is there any issues leaving the extended pins in either pistol and going back to a stock hammer spring?  anyone done this with no ill effects?

Never tried that but the claim from CGW is that full power factory hammer springs used with the extended firing pin could result in pierced primers.

   Per the part listing for the Non Firing Pin Block Extended Firing Pin, CGW suggests not exceeding a 15# Hammer Spring with the Extended Firing Pin installed. I assume that this also applies to the Extended Firing Pin for Firing Pin Block pistols.

"Use with a 15# hammer spring or less."
Will work for CZ pics! (including but not limited to all CZ clones)
