That's the question. Why did you choose the type of concealed carry handgun you carry now? What features and materials does it have and why do you prefer them? For me it is a Glock 27 .40 S&W. I have always been a fan of polymers for the light weight. After all, if I have to keep it concealed, I want it to be comfortable during all day carry. I don't want it too light though, then recoil will be a problem. Glocks are also known for their durability and ease of use. No manual safety. Just draw, point and shoot. I also chose the .40 S&W due to the fact that it has the power I wanted to ensure the job will be done right if it requires. I trust a 9mm, but figured why not get a .40 in the same size package?
