My P220 was 100% reliable, except for one batch of IMI ammo that was uncrimped, and would not work in any other weapon, either. (The case mouths were flared a bit.) Now, I must use a .40 DA auto as a duty pistol, and as the P229 is on the approved list, I carry a P229, which is also 100% reliable. I am acquainted with quite a few of my co-workers, who carry a variety of pistols, and I have heard of NO problems with SIGs, and this includes P220s that were "grandfathered" from the old firearms policy, when .45s were OK, and the P220 was immensely popular as a duty pistol. I was stupid, and only grandfathered 1911 pistols, during a time of temporary insanity. It's OK, though, as the P229 fits my hands better than the American-style P220. All manufacturers have managed to produce some lemons; keep in mind that it is the unhappy customers that make the most noise. Satisfied customers tend to be a silent majority.
