Have a Glock 17 Gen 3 that's about 1500 rounds old and noticed its starting to slam fire (slide locked back, new mag inserted, release and boom without trigger pull).
I found that sometimes when I pull the slide back and let it fly, the trigger pin sear misses (fails to engage) the trigger...
So with the slide locked back and when I slam the mag in...why does the slide sometimes decides to go forward?
I'm trying to recreate it, sometimes it does and sometimes it stays locked back.
Is there certain trick or scientific explanation?
Gun in question is a rental Glock 19 Gen3...
