DPM System for Glock Pistols, Glock 17/22 Gen 5 (Adjustable)

DPM System for Glock Pistols, Glock 17/22/31/34/35/37 Gen 5 (Adjustable)

The DPM "Full Adjustable" System is a mechanical recoil reduction system for Glock Generation 5 pistols. It replaces the original recoil spring assembly and works with a tuned multi-spring system consisting of outer and buffer springs that significantly reduces felt recoil – tuned for both factory pistols and customized firearms.

Shortly before the slide's rear stop, the additional buffer spring builds up counter-pressure, braking the slide in a controlled manner and preventing hard impact. The result is a smoother cycling process, less muzzle rise, and noticeably better control over the firearm. The combination of 4 outer springs and 6 buffer springs provides 28 adjustment options, allowing the system to be precisely tuned to ammunition strength and shooting style. For those who prefer the classic design with a fixed guide rod, the captured DPM variant is available here.

Advantages at a glance:

• Extremely fine tuning with 28 adjustment options for almost any ammunition and shooting style
• Noticeably reduced recoil and less muzzle rise for faster and more precise follow-up shots
• The dampened slide stop protects the slide, frame, and a mounted red dot sight, extending its lifespan
• Self-locking spring plug prevents feeding malfunctions and stoppages
• Suitable for factory and tuned pistols – ideal for sport, competition, and training

Features:

• Two-piece, telescoping guide rod made of steel
• 4 outer springs: 3.8 / 4.0 / 4.2 / 4.5 kg (approx. 8.4–9.9 lb)
• 6 buffer springs in two wire gauges (0.7 mm & 0.8 mm), each in short/medium/long: approx. 8.5–11 kg (18.7–24 lb)
• In total 28 individual spring combinations possible (including operation without buffer spring)
• Direct replacement of the original recoil spring assembly without modification to the firearm
