First of all I have a Gen4 26 and Gen4 19. They work well and I carry both. I was told the 26 would conceal better than the 19 amd print less because of the length of the grip. I found this to be true. Ok the single stacks like new M & P Shield are thinner, but the grip is longer than the 26. I believe that grip length not thickness is the MAIN factor in concealment. So the 26 should print less. The single stacks I have read about should be more comfortable when sitting down, etc. because it is thin but not more concealable. What does everyone think? I do plan on an M & P Shield not because I need one, but because I want one for my collection and I want to collect a couple of M & P's. :embarassed: Wanna kill these ads? We can help!
