About the Gun

This is a full-size, single-action 1911-style pistol built on an all-stainless-steel frame and slide. It follows the classic Browning short-recoil, locked-breech design with the traditional grip safety and manual thumb safety. Early examples were offered in Nitron or stainless finishes, with or without an integral accessory rail on the dust cover. The slide carries SIG’s distinctive contour and rear serrations, while the overall proportions and weight give it the solid, full-size 1911 handling characteristic of Government-model guns of the period.

Analysis

SIGARMS introduced the series in 2004 as its first dedicated entry into the 1911 market, branding the initial full-size models GSR (Granite Series Rail) in reference to both the New Hampshire manufacturing location and the rail featured on the earliest guns. Design input came from competitive shooter and pistolsmith Matt McLearn, with early production relying on frames and slides from Caspian Arms plus other specialized components before the company shifted more manufacturing in-house. The line later carried the Revolution designation as the model range expanded and the corporate name changed to SIG Sauer; by the early 2010s the GSR and Revolution markings had been dropped in favor of the simpler SIG 1911 designation.

Nice 1911

Great .45 but it's not my favorite. I prefer the Springfield milspec. This is a sharp looking gun, with some nice features. But you really feel the bulk/size on this gun.
