I have a S&W M&P9. I actually have it listed for sale or trade but cant decide. I have a Glock 26 which is smaller than either. It carries well and is compact. It shoots within combat accuracy quite well and is argubly one of the greatest CCW on the market. My 26 just doesnt fell right. I cant complain though and find it easy. I purchased the M&P9 because I was curious and wow I really like. I like the interchangable back straps and the feel just fits. The full size is a little large to be carried in the appendix position but I dont feel that carrying it at 3-4 o clock position would be a problem with a little cant. I love the way it shoots. Its in awesome shape and I dont think I could replace it down the road. I guess my issue is its a little tall meaning it prints a little under a t shirt. I have considered the M&P9C. I figure it will feel the same but be a little shorter. I like the M&P triggers and they feel good in my hands. I think the compact is going to be the perfect size.
