From my understanding the extractor, mag, and everything is the same between the 31 and 22 models. So I got a glock factory g22 barrel, and shot 100 or so rounds yesterday at the range to test it out. It went through without a hitch, but for when I was picking up the brass I noticed a mark on the top and a slight dent.
Any ideas, is this an issue? If the extractor, and Mag is the same do g22 mark their cases like this?
