My favourite gun.
That along with the Revolver and its explosive attachment upgrade.
lol, in Human Revolution I was going for the no-kill stealth run(I didn't get it as I hit a few headshots with the tranq).
In one instance, I saw a ton of enemies and couldn't figure out how to get around them;there was a LOT of them.
So I pulled out the revolver, fired a single shot into a wall, ran into a hidden spot, and let the enemies investigate while I scurried away.
I was so proud of myself for that. A friggen loud ass revolver ended up helping me in my stealth run. hahaha
