Browning HiPower
I don't know. There are some good 9mm that are small, but I'd say it would depend on your hand, body size, grip size, etc. If you're big, then a tiny toy sized weapon wouldn't be good. Moreover, it would be hard to handle in an emergency situation. Also, will you conceal in a pocket, pants, jacket, backpack, etc.? For me, I really like the Browning HiPower. I'm 6'1" and 230lb, and it really fits my hand well without being too small. The width of the HiPower is VERY narrow. Almost unbelievably so. Even with a 13 round clip. Easily tucked and invisible, but I like to use a pancake holster and a shirt untucked. But, that's me. I like what the other posts say too. Frankly, I can carry my full sized 9mm Beretta and no one notices.
