John posted some of his experiences with Rings Blue Guns and they weren’t all pleasant. I figured I would weigh in also. I have only made one purchase from Rings. That purchase was a Springfield Armory XDm Blue Gun. The Blue Gun says XDm .40, but they are basically the same gun when it comes to external shape. You can look at the close-ups and see the finish on the blue gun. My biggest annoyance is the grip safety that sticks out of the blue gun. It cannot be depressed and really messes with your grip. Maybe it’s just me, but it seems that this is a major oversight. I eventually ground it off and made some other modifications that I’ll tell you about later. All these photos are pre-modification.
