My 220 ST is VERY accurate. So accurate, in fact, that I had to buy a 226 ST to keep it company. Just shot it last weekend, and it's every bit as accurate as the 220 ST. Only difference is, I have to use a bull hold w/ the 226 ST and a 6:00 hold w/ the 220 ST. These guns are sweet shooters, boy, and the additional weight really makes recoil a non-issue. I'm in Sig heaven, baby.
