7 yards should be fine. Practice drawing from concealment and pulling that trigger until it is automatic. Also practice clearing a misfire or stovepipe. As stated above, when you hear the muzzle blast of your opponent, you don't think real clearly. My Department makes us qualify out to 25 yards, but the most practical, in my experience, is 5 shots, from the holster, in 4 seconds at 3 yards.
