Looks kinda like a Super Redhawk, 357. Not that up on my firearms any more though. New, several hundred bucks in a gun shop; on the street, you can probably name the price if you don't insult the L out of someone.
JMHO, but I'd stay as far the fuck away from any of this crap as possible.
Guns & alchohol don't mix; what in the fuck do you think about guns and weed ?
And, it's double time in the state I live in, to even have a weapon in your possession if drugs are found there too.
Just my advice, and you can say fuck me, whatever....it's a really bad scene !
