Rimfire A place for the rimfire variants of AMT, the lightening pistol & rifles along with the AutoMag II: 7: 29: Baby Automag Marking By John Nada 04 Mar 2021 at 9:53am. My serial number starts with a 'M' I've seen a bunch for sale on gunbroker, but they all start with H. Anyone have any ideas what M stands for? I think it should be an earlier model, but honestly I have no clue where to begin. Numrich Gun Parts Corporation 226 Williams Ln. Kingston, NY 12401 Phone: 866.686.7424.

Our Assessment: The .44 AutoMag was made famous by Clint Eastwood as Dirty Harry when he described his new backup pistol in Sudden Impact: “Well, this is the .44 Magnum Auto-Mag and it holds a 300-grain cartridge and if properly used, it can remove the fingerprints”. In 1970, Auto Mag Corporation president Harry Sanford opened a factory in Pasadena, California under the moniker “AMT”. The first Auto Mag was shipped on August 8, 1971. In order to show a huge market demand in order to attract investors, the company priced the pistols at about $1000 less than it cost to make them. Alas, the factory declared bankruptcy on May 3, 1972, after making fewer than 3000 guns. Sanford later opened a succession of other companies (TDE, OMC and IAI) to make the Auto Mag and other pistols he designed, and was contracted to manufacture the Auto Mag for High Standard. This is one of the early AMT Auto Mags, with a Pasadena address on the receiver even. The Pasadena made pistols are regarded as the best of the Auto Mag line, having been subjected to the best quality control and being milled from Carpenter 455 stainless steel stock. This pistol is in about Very Good condition with 90% of its original finish remaining. It shows finish loss on the frame and marks on the barrel and receiver. The checkering on the exhibits minor wear and the bore is bright with sharp rifling. This would be a nice addition to any collection of semi-automatic pistols. Some people collect just Auto Mags – with the differences in receiver addresses to choose from, as well as custom guns by Jurras and Lomont, it takes a lot of work to gather a set of “one of each”. Besides, who wouldn’t want to own a gun that “if properly used can remove the fingerprints”?
