The AMT Hardballer is a series of pistols that are part of the 1911 platform (based on the .45 ACP M1911) made by Arcadia Machine & Tool (AMT) from 1977 to 2002. [1] The Hardballer was the first entirely stainless steel 1911 pattern pistol. [2] Other features included adjustable rear sights and a lengthened grip safety. [3]
The pistol's formal U.S. military designation as of 1940 was Automatic Pistol, Caliber .45, M1911 for the original model adopted in March 1911, and Automatic Pistol, Caliber .45, M1911A1 for the improved M1911A1 model which entered service in 1926. The designation changed to Pistol, Caliber .45, Automatic, M1911A1 in the Vietnam War era. [10]
The .45 ACP (not to be confused with .45 Colt) cartridge is a very popular caliber due to its low velocity and relatively high stopping power. This caliber is associated most with the Colt M1911, logically, as ACP literally means 'Automatic Colt Pistol'. However, there are many more guns and variations on the M1911 that are chambered in .45 ACP.
RIA (Rock Island Armory) 1911s are derivatives of the US Military G.I. M1911-A1, the standard issue US Service pistol from 1911 to 1985. [3] Most RIA models are targeted at the low-end price point of the 1911 pistol market and are basic entry-level MIL-SPEC versions of the 1911. [4] However, some models offer additional higher-end features.
Models in use included the M1911A1 (Colt .45 Automatic), Smith & Wesson (Combat Masterpiece in .38 Special caliber), Smith and Wesson Model 1917 (.45 ACP and .45 Auto Rim) and various other small arms.

John Browning's 1911 .45 ACP has been used for many cartridges over the past century. In every instance the cartridge used a bullet with a diameter that was the same or smaller than the original .451". Both the Desert Eagle and the LAR Grizzly have been offered in cartridges of .50 caliber. Both are large cartridges requiring a large, heavy pistol.
