DPM Mechanical Recoil Reduction System for Glock 26 / 27 / 28 / 33 / 39 (Gen 1–5) – Slide Extended System *B.O.S.S.

DPM Mechanical Recoil Reduction System for Glock 26 / 27 / 28 / 33 / 39 (Gen 1–5) – Slide Extended System *B.O.S.S.

 Notice: This particular model system protrudes from the slide by design and is intentional.

Enhance the performance and longevity of your subcompact Glock with the DPM Mechanical Recoil Reduction System – Slide Extended System (B.O.S.S.). This patented system is engineered exclusively for Glock 26, 27, 28, 33, and 39 (Generations 1–5), combining innovative recoil control with extended slide operation for compact frames.

What is B.O.S.S.? The “Slide Extended System” uses a proprietary plug (bushing) that expands internal slide space, allowing subcompact Glocks to house DPM’s multi-spring recoil rod system effectively. The result is improved recoil management and enhanced cycling—without modifying your pistol's frame or slide.

Inside the recoil rod, a third internal spring controls slide impact, preventing the slide from slamming into the frame. This design not only reduces felt recoil but also extends the service life of your firearm.
