Ruger Security 9 Compact Magazine Adapter Compatible With Security 9 Magazines

The Ruger Security-9 Compact magazine adapter from Ruger converts a standard 15-round 9mm Luger Security-9 magazine to fit the 10-round configuration of the Security-9 Compact, providing a simple, factory-compatible solution for shooters who want to use full-size magazines in a compact platform; molded from high-quality polymer with a matte black finish, this adapter preserves proper feed geometry and follower alignment to maintain reliable cycling and consistent performance at the range or in field carry. Designed specifically for the Security-9 Compact, the adapter installs quickly into Ruger 15rd magazines and functions as a discrete, durable spacer that keeps the magazine profile low while allowing the shooter to leverage existing magazines across pistol models, making it ideal for range practice, sectional training, or reducing the number of magazines needed for multiple Ruger pistols. As a Ruger factory part, the adapter matches the OEM fit and finish expectations and integrates cleanly with Ruger Security-9 magazines for a seamless, professional result.
