Yes, .38 Special (wadcutter) in a 1911a1. Jim Clark made some a few years ago. And I know that the Peters Stahl was once chambered for it. It made a good trainer with little felt recoil, used the same frame as the .45 ACP, so change the top and mags and you were back to .45. Are there any manufacturers doing that now?
