Just got in from the range. Ran almost 200 rounds through my SR9C. Mixed lot .... 115 gr WWB FMJ, Federal 115 gr FMJ, Remington 115 gr FMJ, Winchester 115 gr HP, Hornady 134 gr +P Critical Duty, and Cor Bon +P124 gr.. Ate 'em all while licking it's chops while spitting out the fired cases! No hiccups. Consistently spinning a 4" metal plate target at 12 yards off handed and many times one handed. One sweet shooting son-of-a-gun!!
