I love my Buckmark. It shoots great and has no trouble with ammo it's designed to use (subsonic isn't a good idea). I taught my wife to shoot with that pistol.

But I would trade it in a heartbeat for the right MkII. There isn't a lot of difference between it and the MkIII when it comes to the way they shoot. A MkII with a 10" barrel and a competition trigger is the most accurate pistol I've ever shot. It's crazy accurate out to about 60 yards. It shoots better than a lot of .22 rifles I've seen.
