I'm now curious if it's the non- Jello action of the frame with the light installed, the weight on the front end of the gun ,or the bullet shape of the hollow point rounds.
Is the slide cycling too fast for the magazine to catch up?
Is the different balance or different Jello action causing the slide not to travel back far enough or too far/too quick?
Would +or- mag springs or +or- recoil springs change anything? Bullet shape does make a difference but I don't want to run FMJ all the time. Do the .45 ACP Glocks have rail mounted issues?
If I'm rambling or whining tell me to shut-up. I'm just thinking out loud at this point. I'll prolly wind up leaving the light off the gun.
