Here is my setup:
Glock 34 Gen 4 Zev Tech Fulcum Trigger Zev Tech Standard Power Firing Pin Spring ISMI 15# Spring
SS Guide Rod
Precision Delta 124 FMJ Tite Group 4.1 at 1.1 OAL CCI Primer
I am not sure it’s me or the gun is jumping too much. When shooting 2-shots fast, a lot of times my follow up shots will be very high. Many times if I hit the zero on IDPA target my follow up will be a head shot. While they are both zero’s, that’s not what I was pushing for.
I don’t notice it when shooting my Kimber 1911 9mm, Wilson Spec Ops 9mm or a SV2011 45ACP.
I have also tried the Zev Tech blue (12) and red (14) springs (the red spring left paint flecks on in the slide). The 15# ISMI spring seems to settle it down some. My thinking is I need to go to an ISMI 17# spring to see if it helps the jumping.
I know a lot of you use 13 and some all the way down to 11 pound springs. Please don’t just throw out there what is good for you. I’ve read 100’s of threads on what is good for who. What I’m looking for is help in why it’s doing it. If pistol cycles, will a heavier spring help? Could it just be me re-engaging before the gun settles? Does the gun run faster and smoother with heavier loads and stronger springs?
Thanks
