Welcome to INGO and Congratulations on selling the Sigma. In my opinion one of the easiest and fastest way to improve your shooting.
I recently sold a Sigma 40 due to the fact that at 20 feet I was doing good to hit a barn with it but at about 80 or 90 feet I could cause great harm to a pop can. Has anyone else had similar issues with this or am I just a better shot at a distant target?
From what I've read / heard, the SD trigger is much improved (shorter, smoother, close to the M&P.) And they've added a night-sight on front post too. I need to check one out - it is on my short list! (I actully like manual safeties, so I'm also looking at the Rugers and Tauruses.)
