Design and fit

This 17-round magazine is built to integrate seamlessly with Ruger Security-9 pistols (full-size models). The flush fit floor plate preserves a low-profile grip footprint while the included mag adapter allows for a more comfortable indexing point when you need the extra capacity. Made in the USA, the magazine reflects domestic manufacturing standards and quality control many shooters prefer. At a street price of $27.89, it’s an economical upgrade for training, range days, or as a ready spare. Shop this product to add an extra magazine to your kit.

Performance and tactical considerations

A 17-round magazine changes how you plan drills and manage stages. For competitive practice or defensive scenarios, the additional rounds reduce reload frequency and allow longer strings between stoppages. The flush floor plate maintains concealment and holster compatibility for those using full-size frames, while the mag adapter offers a positive purchase when you need a bit more grip during extended strings.

Compatibility notes

Do not install this magazine in a Ruger Security-9 Compact—fit and function are specific to full-size models. The product is listed under Ruger with model designation Various, meaning it serves as a direct-fit aftermarket replacement across compatible Security-9 full-size variants.
