I’ve been thinking getting into gaming, it looks like USPSA has the most options. I see EAPS, Tangi, Cajun action, and gulf coast. How to choose a good chapter for beginners? I shoot a Beretta 92 and a red hill tactical holster with just thumbscrew friction retention. Will this work or is it a Glock world? I also have an AR, can a uspsa pistol rig be setup that works well in 2gun/3gun or would two different belts be needed? Id been interested in PRS/NRL but I dont see a presence in LA.
