I ran across one of those cool K-frame 9mm Smith & Wesson revolvers at a November gun show. I don't recall what price he had on it, but it wasn't outrageous.
I could really see me buying that if I spot it again, or spot another. It's pure Smith & Wesson, but different than most any you've seen. Really interesting is the breech face of the revolver-- there's the hole for the firing pin and a second hole there as well. I believe it was meant to hold or steady the 9mm cartridge.
I'd like to own one and give it a twirl.
Attention Brass rats and other reloaders: I really need .327 Federal Magnum brass, no lot size too small. Tell me what caliber you need and I'll see what I have to swap. PM me and we'll discuss.
