I wanted the same thing. So I went with a Gemtech MULTIMOUNT, it has user replaceable end mounts. With a Gemtech L.I.D. recoil booster my G27 (converted to 9mm)cycles flawlessly.I even use it with a.380 converted Makarov with a solid mount,also sees use as a subcaliber can on all my .22LRs! They even have three lug end mounts!
