I have recently switched from the Serpa to the Safariland holster. My primary use is for gaming. USPSA/IPSC/Steel.
This one from Safariland is based on the "women's" version, but was modified by me to be USPSA legal. The last pic shows a spacer that pushes the grip away from the body.

With a hair drier, I brought the outer tilt in to the legal 2" standard.
This makes the draw very fast, as I can get a full grip without fighting my love handles.
