Thought I'd see what I could come up with on the Web. I googled in "44 Auto Mag magazine" and came up with a "Guns & Ammo" magazine article. A Big 50 (years) For the 44".
Where do you even find ammunition to put into your magazines?- Let alone, find additional magazines. This article mentions your 44 Auto Mag, as introduced by AMT's founder, the late Harry Sanford, who fired a rimless version of the .44 Magnum that was originally developed by bobbing and modifying .30-06 cases. Ballistics were on a par with the revolver round. Several manufactures eventually made versions for the Auto Mag. Less than 9000 were produced, and today they are pretty hot collectors items.
This article also includes a picture of the 44 Auto Mag. ... Nice.
Continuing my search for the ammo-type "magazine", I found:
>>>>>>> ammoclip.com <<<<<<<
On the left side of the Homepage "click": >> 1911 thru A <<
On the left side of that page "click": >>>>> AMT Automag <
On the left side of that page "click": > Old.44 AMP/357AMP <
There you will find a couple "magazine" pics. and text:
"Auto Mag old .44AMP & .357AMP, blued steel body and floor plate with alloy follower, unbranded-new." Also, "Limited to stock on hand." >>>> $40.00 each <<<<
"If an item is listed with a purchase button (and is) there is a 99% chance it is in stock."
Good luck, and congratulations- You have a very interesting and unique handgun. Maybe you could post us a pic.
