Bought this a couple of months ago.  200 rounds later, I have confirmed that I shoot better with a 1911.  My loss is your gain, as they say.  Here is what Sig says about this fine, fine gun:

The 226® X-Five Tactical utilizes a light-weight alloy frame with a Picatinny rail to provide the tactical edge. Features include ergonomic beavertail grip, standard single-action trigger w/ ambidextrous thumb safety, SIGLITE® Night Sights and polymer grips. The X-Five Tactical is nimble without sacrificing natural pointability and balance. The Tactical comes with two 10 round magazines in 9mm and is finished in hard black anodize.
