Apparently TDI has produced a civilian legal semi-automatic version of their KRISS 45 Carbine. Quite a futuristic looking firearm, which supposedly reduces muzzle climb by 95% for the .45 ACP cartridge. You’ll recognize that as quite a feat if you’ve ever tried to keep a 1911 or even a Thompson level in rapid fire. ImpactGuns is sold out, but there’s always the waiting list.
