[JD Miller]

Who has tried the HS 12000 11.5#  hammer spring... ? Im thinking about including it in my order to add to the kit im getting

Do you get primer miss fires with any ammo ?

I see CGW has a  HS-8500 (8.5#) hammer spring for use with 'soft' Federal Primers only also

I have the HS12000 spring in two of my CZs.  Recommend you also get the extended firing pin and reduced weight firing pin spring as well.  That combo reliably ignites CCI and S&B primers.

All that is included in the kit im getting

Just wondered about the 11.5 hammer spring not setting off hard primers

I've got #13 Hammer spring. Extended firing pin not required for anything I've shot. (Even it was recommended)
I'm pretty sure you won't have any problems with #11.5 hammer spring with extended firing pin and reduced power firing pin spring.
