I own a .40 BHP, which I love. Together with HK USP, it's my favorite semi-autopistol. I am usually not the kind of person to buy more than one example of a particular gun, but in this case I might make an exemption. My question is: does 9mm BHP handle and feel significantly different from it's .40 cal cousin? I know that the weight and dimesions are slightly different, and of course 9mm is a softer shooting caliber, but does the overall shooting experience make it feel like a different gun?
