The AMT Backup was first known as the OMC Backup. This early variant was produced in .380 ACP caliber in El Monte California. OMC produced a short run of these pistols before the molds were purchased by Arcadia Machine & Tool who took over production. The original AMT Backup was produced with a single-action trigger mechanism while the later Backup II used a double-action-only mechanism.
