Well, I think this is a dandy project. No need for a custom cylinder - S&W made 10mm cylinders for N-frames for the Model 610. Just order one of those and install it in your Mod. 57. You'll then have a "pinto" 10mm/41.

I think you guys are missing his point. I think he wants a revolver that will shoot the bullets without spinning them so there's no rifling marks for the forensic's guys to trace back... The 10mm bullet "gliding" along on the surface of the 41-cal's lands ought to still fly fairly straight for a little distance, and that's all handguns are good for, right?











Sorry, couldn't resist!
