Any level 2 or 3 Safariland will do just fine. I use and suggest the 6280 model. Safariland retention holsters are 100% good, all of them. Pick one you like, and you'll be fine.
Any second now people will be coming by to suggest Blackhawk Serpa holsters. I suggest against these generally for the reasons of Tex Grebner and his 1911 (look it up on youtube) though you're safer with a DA pull, but you still have the issues of inferior reliability if any obstructions get into the mechanism, and an obvious release button, and rapid holster wear on your guns finish.
