I know that S&W Sigmas had their growing pains, but I have noticed more people here saying they were a decent gun rather than trashing them. I'd like to hear the experiences of people who have purchased late model Sigmas (particularly in 9mm). My brother is trying to buy a Glock 19 on a budget and I'm not finding any below $450ish. So I want to find out if a Sigma is an alternative.
