I would like to see a S&W 500 chambered for .223. It might not take the pressure, but the cylinder looks long enough, and you could probably bore it for at least eight rounds, and maybe ten. Now that would be a hunting pistol!
and heavy to CCW, hmm? it's just a toy. Ditto those with no concern for speed of repeat hitting. If all you want is a toy, why not stick to playing tiddlywinks? then we wont mistakenly count you as a "progun" voter.
