My father and I went to the gun show to look at some options for a pistol for him. I recommended some of the standards, but he wants to keep the price down in the economy range. He was looking at the s&w sigmas, and then we came across the sig p250 in 9mm and 40sw. They were selling for $339. I am a big fan of sig's, but I am totally unfamiliar with this entry-level model. What do you guys think of it?
