Just to dispel the myth once and for all, NO modern-production firearm, imported or otherwise, can be sold through an FFL without meeting the fed's standard for drop-safety. The idea that a revolver dropped on its hammer will result in a negligent [accidental?] discharge is anachronistic given mandatory MODERN design.
Damn shame it wasn't the case when my roomie forgot to replace the holster thong over the hammer of my Ruger Single-Six Convertible with magnum cylinder in place. 'Course it was decades ago...but I've never forgotten the noise [and threat to my big toe] that resulted from my slinging the Bucheimer western holster over my shoulder and watching the Ruger slide out and go BANG!!! next to my right foot.
The federal standard isn't a guarantee of fool-proofery, but it is pretty robust. Of course, all safety rules apply if your brain still works...but I've no fear of carrying a modern revolver, replica or not, with a round under the hammer.
