Hey Guys, quick question if someone can check for me. From what I remember when I first got my Glock 19 and 21 the gun would still function fine (fire, reset etc) when the trigger housing pin was removed from the back grip. Now neither of them do. Can someone test with theirs? I think maybe when my gun's were new they were stiff so the trigger housing block stayed in place, now that they're worn in maybe it doesn't. Just curious.
