It’s a stock gen 5. I was conscience of not being on the lock but I’m not sure what else it could be.. im new to reloading so I’m unsure. My plan is to back down the charge a bit and see if it fixes anything.

Need advice : 3.8gr of titegroup with blue bullets 125g coated OAL 1.114. Slide sometimes locks back with a full magazine Glock 19. I was 100% off the slide lock. Can high or low pressure cause this? I can’t imagine the pressure is too low. Brass looks ok, no signs really of either. I don’t have a chronograph so I’m sure of velocity. I plan on making some @3.6 and 4.0 to test Thoughts?
