Ruger American Pistol Compact Magazine Adapter Polymer 9mm Luger Compatible

The Ruger 90620 American Pistol Compact Magazine Adapter by Ruger lets owners of the full-size American Pistol easily convert a 17-round 9mm Luger magazine for use in the American Pistol Compact, offering a simple, durable solution for carry, range, and training needs; molded from impact-resistant polymer with a low-profile black finish, this magazine adapter functions as a mag sleeve that preserves reliable feeding and a consistent polymer follower while aligning the longer magazine to the compact grip geometry, improving ergonomics and control without altering the magazine body. Designed specifically to fit Ruger American Pistol Compact models, the adapter installs quickly and maintains the magazine's original capacity and function as a full-size 17rd source when used in compact platforms, making it ideal for shooters who want interchangeability between full-size and compact pistols, streamlined magazine management at the range, and a lightweight, corrosion-resistant option that blends form and function in a handgun magazine accessory.
