Guncrafter Industries introduced the 50 G.I. round and the 1911-style handgun to shoot it around 2004. The round is an strange thing in this day of bigger, faster, stronger. There is no comparison between this round and the 50 A.E. or the 500 S&W. This round is 50 caliber, but with energy similar to 45 ACP or a light 357 Magnum.

I like the idea of a 50 caliber round that will fit in a slim 1911 package, but I would have hoped they would have loaded this round to at least 10mm power. The Bren Ten, a copy of the CZ75 (which itself was derived from the Browning HP) handled the 10 mm under full power loads. Kimber, AMT, and Colt (and others) all offered full power 10 mm rounds in a 1911 package. I hope the 50 G.I. gets a power upgrade.
