Ruger SR9c/SR40c 17-Round Magazine Sleeve

The Ruger SR9c/SR40c 17-round magazine sleeve is a simple, practical solution for shooters who want the ergonomics of a full-size grip when running compact-frame magazines in their SR9c or SR40c pistol. If you've ever felt your pinky wanting real estate on a compact gun's magazine, this polymer sleeve extends the grip to accommodate full-size SR9/SR40 magazines, turning your subcompact into something genuinely comfortable to shoot all day at the range or in training.

Built from polymer, the sleeve is light and durable—no unnecessary weight or complexity. It's designed specifically for Ruger SR9/SR40 full-size magazines, which means you get reliable fitment without fiddling. The benefit here is straightforward: if you already own full-size mags for a SR9 or SR40, you can use them in your compact without losing your grip or dealing with a magazine that protrudes awkwardly.

This is exactly the kind of accessory that makes a difference in real-world shooting. Many compact-pistol owners carry a full-size gun at home or at the range and a compact as a backup or for travel. This sleeve bridges that gap, letting you standardize on SR9/SR40 full-size magazines across your lineup and choose the compact frame when you need it without sacrificing how the gun feels in your hand.
