Sometimes you go out into the world seeking the unusual. Very rarely does the unusual ring your doorbell! From a friend that I jokingly call the "curator of misfit firearms" comes this:
An AMT Hardballer long slide! 7 inch barrel, caliber .45 ACP. In stainless, but galling was a problem with these handguns. It was introduced in 1980. Someone has spent some time and money on it, and it does shoot well! Not my brand of choice, but something to entertain me today at least!
