Help With Cleaning My Glock 19
I'm a complete novice when it comes to guns and this may be a stupid question but here goes:
I field stripped the gun and the part on the slide where the casings come out on the inside on the rear sight side there is what was a silver circle with a pin coming out. Do I clean all of the silver pieces so that they are sliver again? Is this possible? Right now they're pretty much black.
