Do any of you inspect your mag feed lips periodically and if so what spec/tolerance? This particular question pertains to a 9mm variety. I took some measurements today of my new Dan Wesson...entry side of chamber and compared to a Glock 19 gen 4 (low round count). Both @ .390”. mags out of the box feed lip gap: #1 = .320” #2 = .325” Chamber was a curiosity but I would like to establish a window to inspect my mags from time to time. Happy New Year!
