CZ 75 Compact, weak primer stike Fixed, Range Report.

[Alpha Sierra]

I fixed the weak primer strikes by replacing the Firing Pin to the longer one that is sold by CGW along with the associated FP spring.

According to CGW, a 15 lb main spring is the lightest that can be used with a OEM firing pin and firing pin spring and not get light primer strikes.

I bring that up for general reference for those who don't know that or missed that statement in CGW's website.

Your right Alpha Sierra, I made that very mistake by putting a 13.5# main spring in.  A case of a little knowledge being dangerous.  I bought the main spring from CZ Custom before even knowing about CGW.    On advice as noted in the previous post I fixed the problem by going to CGW and  buying the Firing Pin and associated springs.   I did notice the caviot on the CGW website.

"I think at this point I need a new rear sight to move the group higher.  This is at seven yards, off hand, 20 rounds of 124 grain and 20 rounds of 115 grain ammo. "

Taller front sights would do the same thing and probably easier and cheaper to do.

Nope.  You need a shorter front sight to move the point of impact higher.

One thing that has helped me remember is "FORS".  F= front sight  O= opposite direction   R= rear sight   S= same direction   (  i.e. if your hitting to the right of the bullseye, move the rear sight to the left to move the impacts to the left towards the bullseye).   (i.e. if your hitting below the bullseye and want to raise the impact spot up towards the bullseye, raise the rear sight or lower the front sight).

My mistake you need to move the front sight to the impact so you are correct shorter front sight
