Main summary

Key takeaways

Product Review

Product Reviewed

  • DPM Recoil Reduction System (multiple-spring recoil reduction guide rod/recoil assembly)
    • Designed for Glock 19 (Gen 4/5 compatible per packaging)
    • In the video: specifically run on a Glock 19 Gen 5
  • Paired with a Radian Ramjet + Afterburner (i.e., a compensated setup)

Main Features Mentioned

  • Multiple outer springs (3 sizes/strengths)
    • Longer = stronger
    • Shorter = lighter
  • Spring plunger + guide rod insert
    • The system uses a plunger-like spring element plus an insert
  • Additional buffer spring option
    • Includes a retaining plug
    • Buffer springs can be added depending on setup
  • Adjustability
    • Packaging claims 10 adjustable settings
    • Adjustment is done by:
      • choosing outer spring strength
      • selecting whether to include buffer spring(s) (and which)
  • Material/comparison mentioned
    • Video also references a tungsten guide rod with a 14 lb Wolff spring as a comparison

Setup / Compatibility Notes (From the Video)

  • Because the pistol is compensated (Ramjet/Afterburner), the reviewer says they can only use the least-powerful outer spring effectively.
  • The reviewer warns that adding buffer spring(s) with the compensator can cause failures to lock back.

Testing Observations (User Experience)

With DPM + Radian Ramjet/Afterburner (Compensated)

  • Recoil feel changed
    • The system reduced/softened felt recoil in the hand
    • Heavier springs/buffer options were described as making recoil feel “lighter”
    • The slide was described as traveling slower / with less energy returning
  • Slide lock behavior depended heavily on tuning
    • With the lightest outer spring + no buffer spring:
      • recoil feel changes were noticeable
      • but lock-back didn’t always occur reliably
    • With other combinations (heavier springs and/or adding buffers):
      • the reviewer says it would not achieve lock back
  • Overall
    • Recoil felt reduced, but reliability/lock-back required very specific spring selection on this compensated build.

With Non-Compensated Setup (Implied)

  • The reviewer states DPM would be more useful on a non-compensated pistol.
  • Reason: you can better fine-tune slide open/close behavior based on ammo and spring/buffer selection.

Pros Mentioned

  • Adjustability
    • Multiple spring/buffer configurations
    • Claim of 10 settings
  • Reduced felt recoil
    • Especially described as softer/less kick
  • Fine-tuning potential
    • More promising for reloaders/competition on non-compensated setups
  • Alternate tested combo (tungsten + 14 lb Wolff) reportedly:
    • Fast target reacquisition
    • Less muzzle flip
    • Slide lock every time

Cons Mentioned

  • Compensated Ramjet/Afterburner limitations
    • Only the lightest outer spring (and no buffer) worked acceptably
    • Even then, lock-back was not always achieved
  • Value concern
    • Around $100, compared to an OEM Glock dual-captive spring system
    • Reviewer implies it’s not worth it for a compensated pistol
  • Possible underperformance vs OEM
    • In slow-motion, the reviewer claims OEM looked slightly better
    • Specifically: less recoil/muzzle dip and faster return

Comparisons Made

  • DPM vs OEM Glock recoil assembly (dual-captive)
    • Reviewer suggests OEM may have had slightly better recoil/return characteristics on the compensated gun (based on slow-motion)
  • DPM setup vs tungsten guide rod + 14 lb Wolff spring
    • Reviewer overall preferred the tungsten + Wolff setup
    • Notably: consistently locked back

Numerical / Rating Info

  • No star rating or percentage score provided
  • Specific spring weight mentioned for testing: 14 lb (Wolff spring)
  • Packaging claim: 10 adjustable settings

Unique Points Mentioned (Consolidated)

  1. Includes spring plunger, guide rod insert, retaining plug, and 3 outer springs (lighter/stronger by length).
  2. Instructions include confirming the chamber is empty and following assembly steps.
  3. On a Ramjet/Afterburner compensated Glock 19, the reviewer must use the least powerful outer spring.
  4. Using buffer springs in the compensated setup can lead to no slide lock back.
  5. DPM can change felt recoil—described as softer kick and slower slide travel.
  6. Heavier springs/buffers were described as softer in the hand, but they did not achieve lock back reliably.
  7. The reviewer achieved reliable lock-back with tungsten guide rod + 14 lb Wolff spring.
  8. In slow-motion, OEM recoil assembly may have appeared slightly better than DPM.
  9. Value conclusion: Not worth it (~$100) for a compensated pistol.
  10. More promising for non-compensated pistols, especially for competition/handloaders who tune ammo.
  11. Not recommended for everyday carry if you’re not tuning multiple variables.

Speaker Contributions

  • Single primary reviewer/speaker (“Outer Heaven Tactical” host/narrator)
  • No other distinct speaker viewpoints materially contributed beyond the main reviewer.

Concise Verdict / Recommendation

Recommendation: Skip DPM for a compensated Glock 19 setup (Ramjet/Afterburner) if you want reliable lock-back and good value. The reviewer says it only works acceptably with a narrow configuration and isn’t worth ~$100 compared to OEM.

DPM is more promising for non-compensated guns, where you can tune based on ammo—especially for competition/handloading.
