No I didn't GB, in fact I wasn't even aware there was such an animal as a 10 rounder .22! Just too use to my Ruger II Target & my S&W 357. I've been looking at the autos in 380, 9MM, 40, 357Sig trying to decide what is best with the possibility of easily changing out barrels for self defense use. I thought he was referring to a competition where only 6 shots are allowed before reloading.
