I use one holster , A MTAC for 17 years with a 1911 kydex body on it when I bought it but when I bought a P320 compact few holsters were around and Comp-Tac only had a P250c body so I tried it with my P320 compact I just bought . That was almost 6 years ago . The P250c body work well for my P320c . Then I tried it other pistols I have like M&P 4.25 then I notched the front edge of the kydex so a M&P CORE 4.25 fit too and thanks to the flexible leather back half it works well enought for my 1911 commander , kimber ultra and s&w 669 worked well . Just need to snug up the belt a bit more for them skinny pistols .
