I'm looking at getting the new AXG module but I'm curious if I can use one of the holsters I currently own. I have a 320 pro with surefire light and a 226 legion with light. Would it fit one of those?

Mine works with my existing P320 holsters, though I've noticed that I need to adjust the holster tensioning screw on my full-size holster (looser with the AXG grip and a full-size slide).
