Adjustable Recoil System for Glock 20 & 21 Gen 5 – DPM

DPM Adjustable Recoil System for Glock 20 & 21 Gen 5 is a high-performance drop-in upgrade that replaces the factory recoil rod with no modifications required. It reduces felt recoil, improves stability, and delivers smoother slide operation for better control and accuracy.

This advanced system uses a three-spring internal design to control slide movement, prevent frame impact, and enhance shooting comfort. The kit includes two spring plugs and four external springs, offering eight adjustable settings to fine-tune performance for different loads and shooting needs.

Built from durable stainless steel with a black oxide finish, it helps reduce muzzle flip, improve follow-up shots, and extend firearm lifespan. Ideal for .45 ACP, 10mm, +P+, and .460 Rowland applications.
