I've been shooting 8grs Acuurate #5 125 gr blue bullet. 174 power factor. I don't see any signs of high pressure. Seems to work well. To fast of a powder?
Ammo-I shoot 125 gr blue round nose bullets. Range picked up brass with whatever powder and primers I can find. OAL 1.120
I changed three springs. The recoil spring to a 16 lbs. The strikers spring to a Glock 6 lbs spring. The extractor spring to a CZ extra power spring with 0.6 cut off.
Works great!
I have had two open gun slides crack. One was a STI DVC 9mm and the other was a custom open gun also in 9mm. Not a lot of round on either one. I was using a 12 lb recoil spring. My question is would a heavy recoil spring decrease the life span of a slide? Would going to a lighter recoil spring help?
Does the magazine drop a little after being inserted? If the magazine drops (is loose) the slide will hit the top of the round causing the round to nose dive. Just a thought.
How much of a disadvantage would it be to run 9 round mags in ESP? I always shoot to slide lock. I want to shoot my 40 S&W Kimber in ESP. I've tried to run 10 round mags and they are not reliable.
