I've been reading the 642 vs Bodyguard .38 thread, and getting an education J Frames, the Bodyguard and the LCR. I can see the appeal of a small revolver as a BUG.
Wouldn't it be nice to have a BUG in the same caliber as your primary pistol? I understand the difference between rimmed cartridges like the .38 Special and rimless cartridges like the 9mm, but haven't revolvers for rimless cartridges been done before? Even with moon clips, it would seem that a 9mm revolver could be useful.
When I search Gunbroker for 9mm revolvers, I see only a few Taurus, Astra, and Charter Arms models. I'm a little leery of them. Any thoughts?
