I'm going to regret this, but: gun nuts, what're the SR4 stats of this? DV, range, mode, etc.
My totally uninformed thoughts were that it's a hold-out with 5P/-1, SS, Hold-out ranges, Ammo 4(b); hold-out class for Conceal, etc. Based on wikipedia.
I'm wondering if the tiny barrel(s) would reduce the .357 Magnum's DV/AP, though. I'm aware that I suggested Heavy Pistol stats, after all. I assume that's the selling point, because otherwise it's just a normal hold-out. The SS and break-action seem like okay tradeoffs, and it lacks some of the nifty features holdouts tend to have (MAD, etc.).
