I have tried the Glock 17, the S&W M&P, and the Sig 320. I was not a fan of striker fired pistols and definitely not a fan of polymer frames. I tried the Sig 320 and liked it so much that I bought one. Extremely happy with it. Great feel in the hand, grip and weight are excellent. Follow-on shots are much easier for me with the Sig P320 than with the other two. Highly recommended. I bought it through my local dealer who didn't have it in stock but ordered one from MD Charlton, and I got a call within a week.
