DPM System for Glock Pistols, Glock 19/45/47 Gen 4 + Gen 5 (Adjustable)

DPM System for Glock Pistols, Glock 19/45/47 Gen 4 + Gen 5 (Adjustable)

The DPM "Full Adjustable" System is a mechanical recoil reduction system for Glock pistols of Generations 4 and 5. It replaces the original recoil spring assembly and works with a finely tuned multi-spring system of outer and buffer springs that significantly reduces felt recoil – suitable for both factory pistols and tuned firearms.

Shortly before the slide's rearmost position, the additional buffer spring builds up counter-pressure, decelerating the slide in a controlled manner and preventing hard impact. The result is a smoother cycling action, less muzzle rise, and noticeably better control over the firearm. With over 10 adjustment options, the system can 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:

• 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
• 10 adjustable spring combinations for precise tuning to the ammunition used
• Self-locking stainless steel spring plug prevents feeding malfunctions and stoppages
• Suitable for factory and tuned pistols – ideal for sport, training, and everyday use

Features:

• Self-locking stainless steel spring plug with black oxide finish
• Spring force freely combinable from outer and buffer springs: outer springs 8 / 9 / 10 lb, buffer springs 17 / 20 / 22 lb (approx.)
• Without buffer spring (Zero-Buffer): approx. 12 lb total spring force
• 10 settings for different loads and applications
• Direct replacement of the original recoil spring assembly without modification to the firearm

Application:
