Milt Sparks, VMII or their new HR-LTD which is basically a thin VMII with all the benefits and the best features.
It is the only holster I can literally sleep with the gun in it. I have them for all my guns, several for 1911 government, Commander and EMP. HK's P30, HK45 & 45c, Beretta 92 & Vertec, SIG 228 & 226 and several more I can't think of at the moment.
Simply the best. The wait and price are more than worth it. I gave one as a birthday present to a budy that only shoots Glocks 19's. Since I gave it to him, it is the only IWB holster he will wear.
I do own many of the other popular holsters, but after after 58 years of shooting, Milt Sparks is the best I have found. I used to like Alessi too, but Lou is no longer with us, and I have not found his shop as easy to work with anymore.
Don't forget, the belt is almost more important than the holster. I have been using Wilderness Tactical belts for almost 30 years now. The 5 stitch.
Good luck.
