Greg 1972 Colt October 2, 2020

After selling one of the "safe queens" that I knew we would never fire, I bought this gun to give to my son-in-law. It can be used for home and self defense, fired moderately and likely still hold its value.

The 1911 is popular among the general public in the U.S. for practical and recreational purposes. The pistol is commonly used for concealed carry thanks in part to a single-stack magazine (which makes for a thinner pistol that is, therefore, easier to conceal), personal defense, target shooting, and competition as well as collections.

The Government Model

There are no fasteners of any type in the 1911 design, excepting the grip screws. The main components of the gun are held in place by the force of the main spring. The pistol can be "field stripped" by partially retracting the slide, removing the slide stop, and subsequently removing the barrel bushing.

We didn't do this in AIT at Ft. Lee, Virginia, but at my permanent duty station at Ft. Carson in Colorado Springs, I attended several training schools as a Unit Armorer and in one class we had to disassemble and reassemble a 1911 while blind-folded in less than two minutes.

Some manufacturers, such as Armscor, Para Ordnance, Strayer Voigt Inc and STI International Inc, offer 1911-style pistols using double-stacked magazines with significantly larger capacities (typically 14 rounds). Colt makes their own 8–round magazines which they include with their Series 80 XSE models.
Safeties: A grip safety, sear disconnect, slide stop, a half cock position, and manual safety (located on the left rear of the frame) are on all standard M1911A1s. Several companies have developed a firing pin block. Colt's 80 series uses a trigger operated one and several other manufacturers (such as Smith & Wesson) use one operated by the grip safety.
