The DeLisle carbine was a conversion of the Lee Enfield to .45 ACP made by the British during World War Two for SOE use. They used modified 1911 magazines to feed, and included a very large suppressor to make the carbine as close to actually silent as a firearm can be. Original DeLisles are very rare and basically all in museums, but Valkyrie Arms made a number of reproductions, and today I have one of those at the range to do some shooting. Let's see how it handles!
