I've had a lot of discussion with fellow shooters and students at my range about the Serpa holster. For the guys who are just range shooters (99.999% of Canadian shooters fall into this category outside of LEO/MIL) I just don't understand why they want a holster with retention, it is never ever going to be needed. If you're worried about running around in a sport, well, you draw before you move, but if you're really concerned you just tighten the retention screws down. On my new LHS and my old Bladetech DOH I could do all the tactical rolls and jumps and turns and the gun wouldn't come out, it was a bit harder to draw if I tightened it that much, but it worked just fine. Of course I never ran it that way at a match, but it was an interesting thing to demo to people. For the other 0.00001% there are numerous other retention holsters out there that will fit the bill, my favorite is the ALS, if you don't know the thumb release is there, you'll never find it. Unlike the Serpa with the great big "look at me" button on the side.
