Jeff, believe it or not, a Performance Center rep was quoted as saying there were IIRC around 150 of these all-black Shorty 45s made, and as 18DAI mentioned, one member here said he had one in his safe, and that it definitely was a Shorty 45 and not a mistaken Shorty 40 Mark III or otherwise. I've never seen one for sale or any pictures of one, but if I ever do, you can bet I will try to get it posted or linked so that we can all enjoy it!
The black Shorty 45 belonged to member shorty40. If you google "Smith Wesson black shorty 45" the thread comes up, but the pics are gone. I have not heard from him in some time.
Member CQB 45 posted the photos for him IIRC. Maybe he still has them. Regards 18DAI
