Reviews & Ratings for DPM Walther P99/PPQ M2/Long Slide Mechanical Recoil Reduction System — 16 reviews — Page 1

You MUST be confident and familiar with the fundamentals of shooting to appreciate/get the most out of this product. I installed this in a P99AS Final Edition.

This product won’t make you a good shooter or completely eliminate the weapon’s recoil, but it will make your weapon much more “snappy” allowing for quicker follow-up shots. Because of this it’s a good modification for the confident/experienced shooter, but not so much for a beginner expecting their recoil to be eliminated or noticeably reduced.

It’s also difficult to install when reassembling the weapon especially compared to the OEM spring. For this reason I would NOT recommend this product for an elderly shooter or someone with hand strength/dexterity issues.

Great recoil reduction and a more solid slide feel.

It came with 3 springs, I used mid & short ones for my 4.5in full size PDP. It does help with felt recoil by about 25%, but hard to rack up and wouldn't lock up after last round on empty mag.

I was a little skeptical about how much real-world difference the DPM system would make for me.
It made a lot.
I use it in both a Walther PPQ M1 4" and a Walther PDP compact with 4" barrel.

Am I more comfortable? Yes. Perceived recoil feels reduced in maximum intensity and more importantly the recoil power curve seems to be spread out over a longer time, and maybe flatter. In both pistol recoil is easier to live with and to manage without a doubt.
Also, the slide does not "hit" my wrist as badly when it reaches maximum travel, and this is especially noticed with hot EDC loads, +P, and NATO loads--especially on those good days when my stance, grip, and wrists are locked right down. There is much less "teeth rattling" and there is less tendency to for carpal tunnel aggravation while the recoil transmits down to the ground.
Overall, I can shoot more rounds in a day with less distraction.

Am I shooting more accurately? Yes, in rapid fire. Definitely when comparing any of the 3 DPM springs to the worn OEM spring there is a difference. I may be more accurate when shooting the heaviest spring compared to a new OEM spring (polymer rod)--they are in a similar or same ballpark as far as accuracy goes, but the DPM is more comfortable and seems to make body stress more tolerable. I plan to check this again but using a Mantis X10 system to try to generate data in this regard.

The non-captured springs are not at all hard to install or swap out once you figure out where your finge...

Excellent product dose it’s job very well. 50 percent reduction in slide flip on my PPq 45 shooting 230 and helps with follow up shots.Very easy to install and change spring weights as well as remove for cleaning. Recommend to anyone.

After running all three springs included in the kit, several times on slow motion video, I really couldn't notice enough difference to make it worth spending $90. The lightest spring in the kit did seem to be a very slight improvement viewing the slow motion video but again, no real felt difference and definitely not worth the money.

Had my questions. Does this really work? I found that the DPM Recoil system does in fact reduce felt recoil but does it make any major changes? Yes
I use the Mantis X system when dry fire and live fire training to check my movement and recoil during training. The mantis showed me consistent numbers against the numbers of the original recoil spring in my handgun. I tested them with each spring and found that although I thought the provided spring gave me the reduced most recoil reduction, it was in fact the middle spring that worked the best. I switched to the middle spring and found out my groups drastically reduced over distance and back on-sight the quickest.

I've purchased this set of springs hoping to reduce the recoil on my Walther P99AS. Not only it made absolutely no difference in the amount of recoil but one of the springs jammed my gun. The slide was locked so bad I couldn't release it myself and had to call the range officer to help me with that.
Unfortunately, the return window had expired so I couldn't return it. I contacted the manufacturer hoping to get a service. The manufacturer had promised a full refund but never followed up on his promise. They just stopped answering my emails.
To sum it up: this thing doesn't work, the customer service is nonexistent and don't even think about using it in a self-defense firearm because it can seriously jam your gun.

4" PDP with an hour at the range with the shortest spring, the recoil did feel better. Sadly the slide was not capable of locking back on an empty magazine. I suspect the results on a 4.5 or 5 would be better. Going to donate it to my brother who has a 5" PDP to see if he has any luck with it making improvement without a reload disability as a trade off.

this is not for the Walther PPQ Q4 TAC!!!!!!It made the recoil really snappy and follow up shots were way off.The DPM web sight has another version for the PPQ Q4 TAC!!!!I would not recommend this product on the PPQ Q4 TAC AT ALL!!!The factory recoil spring and guide rod are really good,just make sure you look on the DPM web sight for proper fitting!!!!!!.
