Good show, Texas Colt!
For years, I would consider the S&W autoloaders, then settle on something else. I pinned my hopes on the Sigma. (Hey, I was young, and very, very wrong.) With the S&W police turn-ins on the market for cheap, I thought back on all the good stuff I'd read about S&W autopistols and "bit the bullet" (so to speak).
My personal preference is for a consistent trigger pull, so I invested less money than a HK costs in a pair of S&Ws, both DAO. I have a 5946 and a 6944. While my skills have sadly if predictably deteriorated due to lack of practice, both shoot well, and both have a tight and solid feel to them. The bigger, steel 5946 is a big solid heavy sonofagun. The smaller, alloy framed 6944 is a bit thick through the grip. Each has gobbled up ammo like nobody's business.
I'm new to them, but I like 'em. I think they were underappreciated "back in the day" and, based on experiences so far, think they're well worth a look, particularly at today's prices.
