I carried a sig p220(.45) and p226 in 9mm, and I owned a 226 in .40. Outstanding weapons, plenty of accessories, reliable, and Very accurate.
If you do buy one, buy the "aftermarket" mecgar mags. They are cheaper, have a slick surface, usually hold more, and work just as good. Mecgar makes the "factory" mags for sig that they sell with the 226's.
My only complaint is the trigger. I'm just not a da/sa, or DAK/DAO fan. But the da/sa configuration is the best IMO of the sigs. The trigger is smooth and has a very clean break. The 226 I had had the SRT trigger and I liked it much better than my 220 that had a regular trigger, which was a longer reset in single action.
Buy it, you won't regret it.
