DPM Systems Springfield Hellcat 3" & Threaded 3.8" Barrel & RDP Comp

DPM Telescopic Recoil Reduction System — Springfield Hellcat (3.0" / 3.8" Threaded / 3.8" RDP-Comp)

Overview: The DPM Telescopic Recoil Reduction System is a direct drop-in replacement for the factory guide rod on Springfield Hellcat variants (3.0" HS-H11, 3.8" threaded, and 3.8" RDP-COMP). The multi-spring telescopic design uses three aligned springs that compress progressively during slide travel to smooth the recoil impulse, reduce peak impact on the frame, and improve follow-up shot speed and reliability.

Compatibility

• Springfield Hellcat HS-H11 (3.0")
• Springfield Hellcat 3.8" Threaded Barrel
• Springfield Hellcat 3.8" RDP - COMP

What’s Included

• 1 × DPM Telescopic Recoil Reduction Rod (drop-in)
• 3 × External springs (short / medium / long, different power rates)
• Spring plug (must be installed with the DPM rod and springs)
• Installation instructions

How It Works

The telescopic rod aligns three springs that engage progressively as the slide travels. This creates an elastic buffering action that controls slide movement so it never rams hard into the frame — reducing recoil impulse and protecting both slide and frame while preserving reliable cycling.

Power Rates (Slide in Battery)

• Short spring: 10 lbs
• Medium spring: 11 lbs
• Long spring: 12 lbs

Total Force — Slide Full Open (approx.)

• Short plug: 16 lbs (approx.)
• Medium plug: 18 lbs (approx.)
• Long plug: 20 lbs (approx.)

Key Benefits

• Reduced felt recoil — smoother recoil impulse for faster sight recovery.
• Improved follow-up speed — quicker, more consistent second shots.
• Slide & frame protection — buffers reduce hard impacts at end of travel.
• Reduced malfunctions — helps eliminate certain jams and failure-to-feed events.
• Tuneable — swap springs and plugs to match ammo, compensators, or suppressors.
• Lifetime warranty — backed by manufacturer coverage where applicable.

Installation & Tuning Notes

• Always ensure the firearm is unloaded and safe before installation.
• The spring plug must always be installed when using the DPM rod and springs — failure to do so can cause improper function.
• Start testing with the medium spring/plug settings and then fine-tune to your ammo and any slide modifications (compensators, ports, threaded barrels, suppressors).
• If you have unique modifications, contact the manufacturer or retailer prior to purchase to confirm compatibility or custom needs.
