If you pick a Hybrid IWB you will find most all 45 fit 9mm holsters too . I used a Comp-Tac MTAC for 18 or 19 years and now have one of there Infidel Ultra Max holsters too I like well and use with a 5" m&p . I have tried a m&p 4.25" 45 in it with no problems . My wife prefers Stealthgear Ventcore mini that she uses for a kimber ultra and a p365xl .
