I have tried MANY holsters. This one is the best for me. Crafted by Nate at the Ugly Bald Guy Holsters.
I like the cant of the pistol. It's more comfortable to me and has less bulk to it by having the beltloops on either side of the gun. You need a good gunbelt to support the weight of the rig/gun. Depending on your size/build/shape, you might want your pants an inch or two bigger in the waist than you normally wear. Stick your hand in your waistband and push out on your belt. Then imagine an object stuck in there all day.
