At the same time Colt’s Manufacturing was rolling out the SP901 Modular Carbine to writers and bloggers at Gunsite, they were rolling out a new version of the 1911. Called the Rail Gun, it is part of their XSE line of 1911’s and features an integral rail for use with weapon-mounted lights or lasers. It is a full-sized Government model 1991 in either blackened or brushed stainless steel, has Novak 3-dot sights, an upswept beavertail grip, and the previously mentioned integral rail. Currently it is only available in .45 ACP.
Michael Bane reviews the pistol for DownRange TV in the video below. From the comments he made, it is obvious that he likes it. I believe he said in his recent podcast that he liked it enough to buy it. When a gun writer buys a gun with his own money that says something.
