I have a SIG 220 in 45. Super gun, reliable and accurate. All of mine have decent triggers. The biggest problem with SIGs IMHO is getting used to the double action first shot and lighter pull for the following shots. Most of the guys using them in our club will place the first shot slightly (not enough to matter) out of the group for following shots. This only applies to the standard SIG system. They have several optional trigger setups and also have short reset systems. Just don't ever get a SIG single stack mag mixed in with your 1911 mags. They will seat and lock a 1911 up nice and tight, don't ask how I know LOL. Don't have any experience with the 250 series.
