I carried a SIG 220 (Old Model) both on patrol duty and on SWAT. I never had a misfire or any problems with it. I was just looking at the brand new version in the gun shop the other day. This has the longer grip angle on it and the light device. I thought it looked 'sweet.' I'd not hesitate to carry a SIG 220 .45 or a SIG 226 in .40 Cal.
