I own a Glock 19, Sig P226 in 9mm and now, a Sig P220. This is my first .45, so my opinion is worth not so much. Ive put 500 rounds through it. Federal Hydra-Shok. At 50 feet indoors, Im able to get >80% of my shots inside a five inch diameter target. For me, thats very good, better than any of my other sidearms, so I have to credit the gun. Its sweet. BTW, no misfires or other problems yet. I love SIG.
