Rock Island Armory M1911A 380 'Baby Rock' .380 ACP Compact 1911, 3.75 in Barrel, Parkerized, 7+1
This Rock Island Armory M1911A 380, also known as the 'Baby Rock,' is a compact 1911-style pistol chambered in .380 ACP. It features a forged steel barrel, a parkerized steel slide and frame, and the classic single-action operation. Made by Armscor in the Philippines and imported by Armscor Precision International (APINTL) in Pahrump, NV, it offers a 7+1 capacity within a 6.63 in overall length, 4.63 in height, and 1.25 in width, with an approximate unloaded weight of 1.47 lb.
The design follows the 1911 platform with a standard barrel bushing and GI-type recoil spring plug, dovetailed fixed sights, and front and rear slide serrations for positive manipulation. Controls include a thumb safety and grip safety, a lightweight three-hole trigger, and a commander/rowel hammer for a familiar 1911 control layout in a smaller package.
Materials and finish are duty-focused: a forged steel barrel for durability and an investment-cast steel frame and receiver, all finished in a uniform parkerized treatment. Black polymer grips feature double-diamond checkering with Rock Island Armory medallions for secure handling.
Sight configuration includes a fixed blade front sight that is dovetailed and screw-retained, paired with a fixed notch rear sight in a dovetail. Markings include APINTL–PAHRUMP NV and ACP PHILIPPINES, reflecting its manufacture by Armscor and U.S. importation by APINTL.
