The best holster is one that fits you, fits your gun and retains it and it's mag properly, and that you can draw from and re-holster the gun with your gear on without ever having to take your eyes off your target to look at the holster.
You notice I didn't bother with paltry brand names or models numbers, as that's pretty much useless, until you qualify the above conditions.

Democracy is two wolves and a sheep discussing what's for dinner.
Freedom is the wolves limping away while the sheep reloads.
Never confuse freedom with democracy.
