I've had a few DW 1911s, and my favorites are SSC and Marksman 40 (essentially a stainless Valor in .40 s&w from the custom shop). Both are wicked tight and accurate. I use them mostly for USPSA. It seems like 40 is not as popular as it once was, but I am set up for reloading and really like the performance of my current load for action pistol sports. It's kind of cool to have an uncommon DW caliber too.
