Arcadia Machine & Tool (AMT) earned quite the reputation with the .45 ACP Backup several years ago. Though the Backup was only offered in .380 ACP recently, now under the High Standard Manufacturing umbrella, AMT is again offering a .45 ACP variant, which it bills as “The Smallest .45 ACP Auto Pistol Ever Built.”

In the upcoming March 2014 issue of Combat Handguns, author William Bell runs the new Backup through its paces. Bell writes, “indeed it is the smallest—just barely. Its overall length is 5.75 inches, its height is 4.06 inches, and it has a width of 1 inch at the grips. While it may be the smallest, at 23 ounces, it’s not the lightest, but then again, it’s all stainless steel; no aluminum alloy or polymer here. Everything on the gun (save the black, polymer, checkered grip panels) that I checked with my magnet was steel. That includes the five-round-capacity magazine, which has the appearance of a cut-down 1911 type.”

So how did this pocket pistol perform at the range? Did it survive Bell’s tough combat drills? To learn more about the High Standard AMT Backup, check out the March 2014 issue of Combat Handguns, available on newsstands and digitally December 17, 2013. To subscribe, go to
