According to Gary Paul Johnston's article in the latest Guns & Weapons for LE, Sig is finally going to bring out their 221. The 221 is a double column .45 with alloy frame and stainless slide. He hopes it will be out in time for the Shot Show. The 221 was rumored to have been in the works several years ago but nothing was ever forthcoming. With luck, it'll have the same or slimmer dimensions as the 226.
