I will be getting a new handgun soon. I'm looking for something that will be a concealed carry gun. I've read, watched videos, gone to stores to hold them, etc. I'm leaning most heavily to the M&P40C. It feels best in my hands. It seems to sit perfectly between the two Glock models as far as rounds it holds. Overall it seems to be have more attention to detail in it's build (metal sites, etc). I like that I can put a larger magazine in it and that I could switch it over to 9mm if I wanted. The trigger isn't bad but the Glock trigger does feel better. If I go Glock, I can't really decide on the 23 or the 27. I know the Gen4 feels better in my hands but I don't know much about the differences. Outside of dry-firing, I've never fired a Glock. I know know about what it's felt like in the store. The things that draw me to the Glock are all really related to it's popularity. There are so many aftermarket things for it... holsters, mags, etc. One of which is that the Glocks have 22LR conversion kits. The idea of being able to practice on the same pistol (obviously with a different recoil) at a much cheaper rate is a kind of attractive. On the other hand... the amount spent on a conversion kit could be spent on a whole new 22LR pistol. As I said, I'm leaning to the S&W40C. Anything I should think about that I haven't? Any great arguments for the Glock to pull me over to the dark side? If I were to go Glock, which should I go... 23 or 27?
