I seriously doubt anyone carries a Sigma as a duty weapon, unless they are something like a Town Marshall in a small town and have to buy thier own. When I take my Sigma to the range, all the LEOs just about laugh me off the range. They usually feel so sorry for me, they let me shoot thier Glocks. Although, I have to admit I do see a difference, it really isn't that great. My gun goes bang when I pull the trigger and the bullet hits pretty close to the POA. I wouldn't argue with them about thier guns, but I do hate to hear them bash the M&P for no good reason, other than they don't own one. My Sigma is dependable, but I do have a minor malfunction occasionally. Not bad enough to cause a bunch of concern, but I'm not sure I'd stake my life on it. It's strange, because I have around 1200 rounds through her and the problems are a random few that I can't seem to duplicate. I figure operator error is probably the cause, but I can't seem to duplicate that either. Started off with a few light strikes when the gun was new that seemed to work itself out, but I experienced a couple of FTE stove pipes out of about 300 rounds the last time I went to the range. Couldn't find any reason, other than possibly limp wristing, so I cleaned her up good and plan to try again. Fortunately, they were easy enough to clear that I think I could do it under pressure. I do keep mine loaded on my night stand. Just wish I had a little more confidence in it. I'm considering trading it off for an M&P.
