+1 to that recommendation. It is now my preferred open-carry and USPSA competition holster. (Unlike the "gamers", I compete with what I live with in the real world.)
I'm down to under 1.5 sec to draw from that holster (which includes releasing the retention button) and put a shot in a body "A" zone of a USPSA target at ten yards. Some might think that's a long time, but I am not a young man.
You only need to be fast ENOUGH.
