im back with my glock 19 with test shooting it.. i think i have almost 200 rounds through it.. just want to know if this is normal.. the locking block pin has a small wear spot right in the middle just wondering is that normal. and my mag, i can take my finger and move it back and fourth. but it does not move unless i do that.. i read somewhere they are suppose to do that so they wont be snug fit to keep dirt out ect... is there anything i should change out with 200 rounds through the gun or am i paranoid? thanks for all the help. also the end of my recoil spring has got small dents in it when it sits in the barrel but i think that is my fault from the why ive took the slide off a few times. but it sits fine in the barral.. and still doesnt have any miss feeds... thanks guys.
