just bought a new beretta 21a in .22lr. first trip to the range the little pistol performed flawlessly. i fired it with aguila sss, remington subsonic, remington viper, remington golden bullet, cci mini mags, and winchester high velocity 40 grn. i even loaded the magazine alternately with subsonic, sss, and high velocity, not a single stoppage. accuracy was pretty good for a pistol this size, a forty or fifty shot grouping roughly the size of a bowling ball at 25-30 feet offhand. i did not shoot it from a bench, but i would expect the groups to improve if i would have. i was wary of the aguila sss keyholing, but all holes in the cardboard were round. there was one that i was a little suspicious about, but closer inspection proved to be two holes almost on top of eachother.
