You're going to want something you can run with. I've been using a 3X-Crown for my 2011 that fits closely, and with the tension adjusted quite a bit. Even with that though, I would find myself holding my pistol while running. But I plan on using my Glock from now on, so I got a Safariland 6377. It provides a fast draw with mechanical retention. A very fast draw.
