My girlfriend bought me one a few days ago and i love it. The trigger pull is a bit strange at first but I was use to it after about three rounds. I carry a Glock 17 on duty and I am better with the sigma. It feels better in my hand, not to heavy, not to large, and I find it's stock sights easier to use than the stock sights on my Glock. And it has a stainless barrel. But I can't find a duty holster for it. And my girlfriend shot it and it did not jam. Every time she shoots my glock she gets a stove pipe, becuase she light hands it. I just can't get it to jam. One thing I don't like about it is the magazine release, it seems very hard to get it to lock a fully loaded mag. You can't just slip it in you have to force it or give it a tap.
