hmmm,...I dunno,...I've seen some serious accuracy from handguns when playing the IHMSA game.
2" at 50 yards doesn't sound like a very tall order for a quality handgun.
Back when I was in the game, the people who were serious about shooting in revolver class were using the big Dan Wesson's,..44 mags,...357 Maximum's,..375 Maximums,..
The better competitors could keep them in a 6" circle at 200 meters.
2" at 50 yards didn't raise any eyebrows.
