From 1977 to 2002, the now-bankrupt Arcadia Machine and Tool (AMT) company of Irwindale, California, manufactured the "Hardballer" - a semi-automatic, all-stainless steel version of the classic Colt M1911 pistol. The sidearm followed the same form and function as the original and went on to include such changes as a larger grip safety, brushed stainless steel finish, wide target-style trigger, and adjustable rear sights. At its core, the weapon remained a short-recoil operated system with locked breech function. The handgun's production was taken over by Galena Industries following the demise of AMT.
Variants in the series included the "Combat Government" / "Government" for the police market (though originally intended for the sport shooting market), the "Longslide" with 7" barrel (and appropriately-lengthened slide), the "Skipper" in compact form with a 4" barrel, the "Commando" with .40 S&W chambering (since improved into a compact form), the "Accelerator" with 7" barrel and chambered for the .400 Corbon cartridge, and the "Javelina", a 10mm Auto model with eight-round capacity magazine. The series has also been seen in the original Colt M1911 .45 ACP chambering.
The original "Hardballer" name was born from the weapon's use of the round-nose Full Metal Jacket (FMJ - otherwise known as"hardball") ammunition. The AMT Hardballer was the first all-stainless steel constructed version of the classic M1911 pistol.
