GURPS Guns: Auto Mag Pistols

Here's another set of hand-cannons.

Auto Mag Model 180, .44 AMP (USA, 1971-1972)

The original Auto Mag Pistol is an over-engineered beauty, mostly cast from stainless steel. It is single action and uses a rotating-bolt short-recoil mechanism to manage the power of its unique cartridge. The barrel has a large rib running along the top, which combined with the guide rods running along the sides and an elegantly curved trigger-guard, gives the pistol a very distinctive appearance.

With a cost of manufacture well below the retail price, the Auto Mag Corporation was only able to build around 3,000 before declaring bankruptcy, six months after shipping the first one. Owner Harry Sanford went on to produce it under several different brands (TDE, OMC, Thomas Oil Company, High Standard, and AMT) between 1973 and 1984, raising the price to $6,000 to actually turn a profit. Despite the cost, he managed to sell around 6,000 more guns. Since 2018 AutoMag Ltd. has sold a copy for $2,500.

Auto Mag magazines cause feed issues (−1 to Malfunction) when fully loaded. See GURPS Tactical Shooting, p. 20.

The .44 AMP round was always difficult to find and expensive, even more so once the guns were no longer produced. Many owners make their own by cutting down .308 Winchester or .30-06 Springfield casings.

The Model 280 changed the Model 180's 6.5″ barrel for an 8″ one. The very rare Model 160 (1972) uses the .357 AMP cartridge, which is a .44 AMP case necked-down to take a smaller bullet. The even rarer Model 260 (1972) shoots .357 AMP from a long barrel. Conversion between any of the variants is simply a barrel-swap (a spare short barrel is $500, a long one $600).
