Ruger Sr9c/40c 17rd Mag Sleeve

The Ruger SR9c/40c 17rd Mag Sleeve is a polymer grip extension engineered to bridge the ergonomic and functional gap between compact and full-size Ruger pistols. Law enforcement and civilian operators who carry the compact SR9c or SR40c often face reduced grip real estate and magazine capacity compared to their full-size counterparts. This sleeve solves that problem by allowing shooters to use full-size 17-round or 15-round magazines in their compact platforms, delivering improved control, faster follow-up shots, and confidence during critical situations without sacrificing the compact form factor during carry.

Constructed from durable polymer, the SR9c/40c mag sleeve extends the grip by approximately 0.75 inches while maintaining structural integrity and reliability. The design accepts Ruger SR9/SR40 full-size magazines, transforming a compact pistol into a firearm that handles nearly identically to its full-size sibling during extended shooting sessions. The minimal weight penalty—0.06 lbs—ensures that the sleeve does not adversely affect draw speed or holster presentation. Shooters benefit from the extended sight radius and increased magazine capacity without requiring a platform change, making this a cost-effective solution for operators who demand versatility across different mission profiles.

This accessory is ideal for concealed carry professionals who transition between duty and backup pistols, firearms instructors managing training scenarios with variable magazine capacities, and tactical operators who prioritize ammunition capacity during extended engagements. Installation is straightforward—the sleeve simply slides over the existing compact magazine basepad. Compatibility is limited to Ruger SR9c and SR40c compact models using standard SR9 or SR40 full-size magazines; verify your platform before purchase. When configured with full-size magazines, the grip extends sufficiently to accommodate all four fingers with proper indexing, significantly improving controllability for shooters with larger hands or those wearing gloved tactical gear.
