Description

DPM Mechanical Recoil Reduction System | Springfield Hellcat Pro 3.7" (HS H11 PRO)

Overview: Upgrade your Springfield Hellcat Pro HS H11 PRO with the DPM Mechanical Recoil Reduction System; a direct, drop-in replacement for the factory guide rod. This high-performance multi-spring system smooths slide travel, reduces felt recoil, and cushions the slide at the end of travel to protect the frame and improve follow-up speed.

Compatibility

Springfield Hellcat Pro (HS H11 PRO) - 3.7" models

What’s Included

1 × DPM recoil reduction rod (drop-in replacement)
3 × external springs (short / medium / long - different power rates)
2 × spring plugs (short & long) for tuning total buffer force
Installation & tuning instructions

How It Works

The DPM system uses a multi-spring telescopic design where three springs compress progressively during slide travel. The internal spring dynamics act as a progressive buffer so the slide never slams hard into the frame reducing peak forces, smoothing recoil impulse, and improving reliability and control.

Power Rates — Slide in Battery (Closed)

Short external spring: 9 lbs
Medium (Gold) external spring: 10 lbs
Long external spring: 11 lbs

Total Force — Slide Full Open Position (Approx.)

With Short Spring Plug: 18 lbs (approx.)
With Long Spring Plug: 22 lbs (approx.)

Key Benefits

Faster follow-up shots — smoother recoil and quicker sight recovery.
Reduced muzzle/slide impulse — more comfortable shooting and less felt recoil.
Slide & frame protection — progressive buffering prevents hard impacts at full travel.
Improved reliability — helps reduce certain jams and failure-to-feed issues.
Adjustable/tuneable — use different springs and plugs to match ammunition, ports, compensators or suppressors.
Lifetime warranty — backed by the manufacturer.

Installation & Tuning Notes

Always unload the firearm and verify it is safe before beginning work.
The spring plug(s) must always be installed when using the DPM rod and springs — omission can cause improper function.
Begin testing with the medium spring and short plug, then adjust springs/plugs to fine-tune performance for your ammo and any slide modifications.
If you have unique slide mods or compensators, contact DPM or your retailer prior to ordering to confirm compatibility or custom needs.
