Cruiser, I am in total agreement about burns. You should not be getting burns from shooting a revolver-the odd spark possibly but not a diagnosable burn. Just my .02, ask them for a 632 Pro. Thicker barrel and probably heftier frame around barrel, six shots, and you can use .32 S&W long for range, and I doubt that round will blow anything up. And if you want a real screamer of a round use the 115 gr HPs, you are throwing an essentially .30 cal slug downrange at some pretty rapid velocities.
BTW, if either of those incidents happened to me, I would call it "blown up". Damn thing came apart under pressure, sure sounds like blown up to me.
You could also pry about a lifetime supply of .327 ammo out of them also if you were so inclined. PM me if you are interested.
