I have a S&W Sigma in 9mm on my hip as I write this. It was my first handgun that I bought with my PTP. I've put over 1000 rounds through it, and not one FTF, or FTE. Trigger is stiff, but if you can shoot a Sigma well you will pretty much shoot other better.
And at $300 it's a buy! Remember Glock sued S&W over copyright infringements. And won! Pretty much a American Made Glock 19...
