The Pachmayr Signature Grips with Backstrap (Model SW-39 / Part #03306) are wrap-around handgun grips engineered specifically for Smith & Wesson 1st and 2nd Generation single-stack 9mm pistols. Constructed from a proprietary synthetic rubber compound moulded over patented internal steel reinforcement inserts, these grips maintain structural rigidity under recoil while fully enclosing the front strap, backstrap, and side panels. They absorb recoil impulse to reduce hand fatigue during extended range sessions and feature checkered side panels with a sculpted left-side thumb relief for unhindered access to the factory magazine release.

• Full Wrap-Around Coverage: Encloses the side panels, front strap, and backstrap for consistent hand placement and grip traction in wet, dry, or sweaty conditions.
• Internal Steel Inserts: Embedded metal plates prevent rubber flex, warping, or shifting under heavy firing strings.
• Recoil Shock Absorption: Specially formulated rubber compound cushions recoil shock from standard 9x19mm Parabellum ammunition.
• Sculpted Thumb Relief: Contoured left-side profile ensures positive, unobstructed clearance to the frame magazine release button.

Who is the Pachmayr S&W 39, 439, 539, 639 Standard Pistol Grips for?

• Competitive Target Shooters — Requires consistent shot-to-shot handling in IPSC or service pistol disciplines, supported by this wrap-around rubber grip which adds 0.3125 lb to 0.35 lb of steel-reinforced mass to dampen recoil and stabilise handgun control.
• Classic S&W Handgun Owners — Upgrades the shootability of original metal-frame single-stack frames by adding 142 g to 159 g (0.3125 lb to 0.35 lb) of shock-absorbing rubber and full backstrap cushioning to reduce fatigue during extended firing sessions.

Less suitable for: Owners of double-stack frame pistols (such as S&W 59, 459, 559, 659, or 3rd-generation 5906/4006 platforms); these wider-frame handguns exceed the physical frame dimensions of this grip and require dedicated double-stack wrap-around grips.
