First off I am new here from Arkansas. I picked up a used glock 27 gen 4 that a cop had he didnt shoot it much at all the gun was scratch free clean and still had the copper grease in it like the new ones he just never shot it. Anyhow I go run 50 rounds out of it this evening before the rain and I went to pick up the brass and 2/3 of them were scratched and bent on the ends. I had a glock 36 and dont remember it doing that is it something i should worry about or will it get better after the gun breaks in? thanks Dave
