Model 500 can fire a bullet weighing 350 gr ( 22.7 g; 0.8 oz) at 1975 feet per second (602 m/s) generating a muzzle energy of over 3,030 foot-pounds force (4.1 kJ). -wiki
I like the S&W 500 for its stopping power too. It’s a little big for concealed carry, but it more than makes up for that by settling things on the first shot.
Note: I am in Maryland, where handguns can be carried only directly from home to the range or gun shop unless you have a CCW license. I’ve been told that I won’t get the permit, since I’m not in a profession that requires carry.
