F.LLI Pietta Long Colt .45 looks like a fun period reproduction.
I have considered getting one, only because my state is open carry and all the banks require a face bandana.
A clone of the Sam Colt's great Single Action Army model. Worked for great grand-dad, and will still work for you today. They really don't get much simpler than that.
I don't think the AD should have handed the gun to Baldwin at all, as a previous commentator has said. But regardless Baldwin shouldn't have failed to check the condition, and should not have pointed it anyone.
