Pachmayr Mag Sleeves for S&W M&P 9C/40C

• Improved Grip Length: This mag sleeve fills the gap created when a full-size S&W M&P 9 or M&P 40 magazine is used in an M&P 9C or 40C, giving the hand a more complete surface and a steadier hold.
• Higher-Capacity Magazine Compatibility: It lets compact-pistol owners use longer full-size magazines while keeping the grip shape more natural, which helps handling during training, range use, or backup-magazine carry.
• Secure Set-Screw Installation: The sleeve slides over the magazine and locks in place with a set screw, so it stays positioned correctly instead of shifting during repeated reloads and firing.
• Polymer Construction: The polymer body keeps weight low while standing up to regular handling, making it a practical accessory for everyday range use without adding unnecessary bulk.
• Made for a Clean Factory-Like Fit: By covering the exposed section of the longer magazine, the sleeve makes the extended setup look integrated and feel less awkward in the hand.

About the Pachmayr Accessories Series

Pachmayr Accessories covers a broad range of practical shooting components built around handling, fit, and recoil management rather than cosmetic changes alone. The series includes handgun and revolver grips, rifle accessories, and recoil pads for long guns, reflecting Pachmayr’s long-standing focus on parts that change how a firearm feels in real use. Within the handgun segment, the line spans everything from slip-on rubber designs to more specialized grip formats for specific platforms and shooting preferences.

What ties the series together is a straightforward design approach: improve control, comfort, and compatibility with minimal complication. Some products in the family are aimed at better purchase under recoil, while others, such as sleeves and extenders, are meant to make compact handguns easier to hold when paired with different magazines or grip lengths. That makes Pachmayr Accessories relevant to concealed-carry users, recreational shooters, and anyone setting up a handgun for more secure manipulation. Across the range, the emphasis stays on durable materials, model-specific fit, and practical upgrades that are easy to add without changing the basic function of the firearm.

About the Pachmayr Mag Sleeves for S&W M&P 9C/40C

The Pachmayr Mag Sleeves for S&W M&P 9C/40C are built for shooters who want to use full-size S&W M&P 9 and M&P 40 magazines in the more compact 9C and 40C pistols without leaving an exposed gap below the frame. That gap is a common drawback of mixing compact pistols with longer magazines: capacity increases, but the grip can feel incomplete and less comfortable. This sleeve addresses that problem by extending the gripping surface so the pistol sits more naturally in the hand.

In practical use, that means better support for the little finger, a more consistent draw and reload feel, and less pinching or shifting where the magazine meets the frame. The sleeve also improves the overall profile of the setup, giving the extended magazine a more integrated appearance instead of looking like an add-on. The polymer construction keeps the accessory light, while the set-screw attachment helps hold it in position on the magazine body. For range sessions, defensive practice, or carrying a longer spare magazine, this design offers a simple way to combine the concealability of the compact M&P with the handling advantages of a larger grip. At 60.00 g, it adds little weight while providing a noticeable improvement in grip continuity and control.

About Pachmayr

Pachmayr was founded in 1929 by Frank Pachmayr and built its reputation around firearm accessories that improve handling and shooting comfort. The company is especially well known for handgun grips, recoil pads, and gunsmithing tools, with product lines that serve both everyday shooters and more specialized users. Pachmayr introduced its first recoil pad in 1949, and its rubber handgun grips entered the market in the early 1960s, helping establish the brand as a long-standing name in practical firearm upgrades.

Over time, the brand expanded into multiple grip families and recoil-reducing products, including items that use Decelerator material. Pachmayr joined Lyman in 1996, and its manufacturing plant relocated to Prescott Valley, Arizona, in 2014. Today, the brand remains closely associated with functional accessories designed to improve fit, control, and comfort on working firearms.
