Hi, everyone. I'm new to the forums but not to Glocks. Own G31, G33, G20, and G21 Gen4. Converted the G31 to a long slide (hence the name) and a long slide .45 conversion for the G20. I hope to learn about other people's experiences, be it good or bad, with these, IMO, brilliant pistols. Wanna kill these ads? We can help!
