The Ruger American Pistol Compact Magazine Adapter (Model 90640) is a straightforward solution for shooters who own both the full-size and compact versions of the Ruger American Pistol in .45 ACP. This black polymer adapter lets you run your existing full-size magazines in the Compact frame, eliminating the need to buy a separate magazine set and giving you more flexibility at the range or in the field. It's a genuine Ruger factory accessory, so you know it's built to Ruger's specifications and will function reliably with your pistol.
If you've already invested in 10-round .45 Auto magazines for the full-size American Pistol, the Compact Magazine Adapter makes switching between platforms practical and economical. It's a common scenario for shooters who carry the Compact but train or shoot competitions with the full-size version—this adapter bridges that gap without forcing you to maintain duplicate magazine inventories.
As a polymer accessory, it's durable and lightweight, with no complicated installation required. Ruger's attention to fit and function means you can trust this adapter to perform consistently, whether you're at the range or relying on your pistol for personal defense.
