The Lyman Fits S&W M&P 9/40 Full Size Mag For S&W 9/40 Compact grip extender is a simple, slip-on collar designed to bridge the gap between a compact Smith & Wesson M&P frame and a full-size magazine. Contoured to follow the lines of the pistol’s grip, it creates a more hand-filling surface for improved control when running larger magazines in your compact M&P 9mm or .40 S&W.

This magazine collar is tailored specifically for the 3.6" M&P compact, helping shooters achieve a more secure and comfortable hold without altering the firearm itself. Ideal for range sessions, training, or as part of a defensive setup that uses full-size magazines as backups, it enhances trigger control and mitigates felt recoil. Built with Lyman’s attention to fit and function, it offers a straightforward upgrade backed by the manufacturer’s long-standing reputation in shooting accessories.
