+1 for a Sigma dude. I love mine! I actually experienced a slight issue with mine and S&W ishaving me ship it back, so I'll get to test out the S&W support... I'll be sure to post about my experience when it's all said and done. As a matter of fact, I will be shipping it off to them today! Aside from my issue, I love it and even still, it has been 100% reliable. I have 400 down the pipe with zero FTF/FTE.
For those wondering, the issue is, if I ride the slide forward when racking it, it seems to snag on something when it's about 4mm from it's normal resting position. Also, there is a clicking noise coming from the trigger area. If I slingshot the slide, it's fine. I am more concerned eith the clicking coming from the trigger area.
Anyway, I enjoy shooting it, hopefully it'll be returned soon so I can get back to the range.
Keep shootin'
