    Hey all,

    I was unhappy with the factory plastic guide rod/recoil spring on my Glock 26,
    never gave an issue just looks cheap.
    I purchased a DPM Mechanical recoil reduction system, and went shooting.

    I shot 100 rounds alternating between the factory plastic and DPM system every
    10 shots(i had enough mags, and field stripping to switch only took seconds).

    It was a clear difference for me in three ways.
    -1st thing I noticed using Winchester white box 9mm with the stock recoil
    assembly my ejected casings tend to hit me in the face or land on my
    right arm more than half the time.
    This was completely eliminated with the DPM system,
    all ejected casings landed 4 or 5 feet from my right foot.

    -2nd thing I noticed was the overall time it took the slide to move rearward
    eject the spent casing and push a new bullet into battery was faster with
    the DPM. Because of this follow up shots felt like they came in faster and I felt like
    I was dumping the 10 rounds faster with the DPM system.

    -3rd thing I noticed was the DPM system corrected the "bottoming out" feeling
    after a shot is fired and the slide hits its furthest point back.
    This relief of "bottoming out" attributed the most to its recoil reduction.

    Overall I was impressed.
    I tried to be very aware of what my hands were feeling as I took shots and noticed the differences.
    It does stick out from the front of the slide a little.
    The second longer spring included is for +P ammo.

    Very interesting! I hadn't heard of such a thing. Do they make it for all Glock models? How did you hear about it? How much did it cost?

    Yes they make it for all Glocks and XD's along with other pistols,
    this unit was $85.00 plus shipping.

    DPM also makes a Magnet driven system as well but
    it will only work on a pistol with a rail and it costs
    a good bit more.

    I saw some impressive videos on youtube of guys running
    dpm's on full size handguns with good results so
    I had to try it for my subcompact.

    Forgot to mention:
    Initially there was a recall on the bushing part,
    but they replaced it free of charge and luckily I found
    out before I used it. The pics are of the correct bushing.
    Also;
    I wasn't sure if the DPM had any kind of break-in
    procedure. I did notice the slide was tougher to
    pull back than normal with it in, so I left the slide
    locked back for a day or so and cycled it several times
    before first use and this def. helped with slide pull.
    I experienced no failures.

    I'm not a tightwad. I spend a lot of money, shooting thousands of rounds through my Glocks, every year. However, I can't fathom spending $85 on such a device. I do install Wolff non-captured steel guide rods and springs on my Glocks, though...at a lot less than $85. My brass doesn't hit me in the face unless I'm limpwristing.

    Your "new, improved" device simply has weaker recoil springs than a stock factory setup; ergo, the faster slide speed. The same thing can be accomplished by using hotter ammo or using lighter springs on a Wolff rod.

    While I have not tried this device from DPM, Mercmar is correct in that the same thing can be done with his suggestion, and it is a pretty common thing to do.

    Have you tried using it with different weight bullets? If it will reliably cycle 115-147gr bullets including SD rounds then it should be good to go. I would put a lot more rounds through it including any of your SD rounds if your G26 is there for SD.

    i understand what you guys are saying about lesser spring weights but i disagree, if the spring setup on the DPM is softer than that WOULD explain the casing ejecting further however it logically WOULD NOT explain the slide moving forward at a faster rate or the elimination of bottoming out, the slide would move slower and you would feel more bottoming out with a softer spring.
    $85 is pricey for a bells and whistles part, but sometimes the right bells and whistles can make all the difference.

    I'm Impressed with the part! Thanks DPM

    I'm always eager for edification. How about posting a reply based on empirical evidence or at least some cogent theory? I've done a lot of experimenting with Glocks, their recoil springs for various calibers and loads, and I always enjoy learning new things.:cool:

    Oh, yeah, it's been a few moons ago, but I also did fairly well at simple h.s. physics! :???:

    For technical data contact DPM, i'm not the designer I just feel it working when I shoot.

    Lighter springs alone aren't quite the same thing.

    A lighter spring will cause the slide to come back faster, and eject harder. But it also allows the slide to "bottom out" going as far back as it can and causing some muzzle flip.

    The idea behind this system, is that a heavier spring that takes over at some point in the recoil process to eliminate that. The weak spring lets the slide go back to its ejection point quickly, then the heavier spring kicks in and eats up more energy before thrusting the slide back home, chambering the next round.

    That said, i am not sure I would spend $85 on it for a 9mm... perhaps a 10mm or something with a lot of snap. I also don't care much for how it sticks out of the end. But all that is OPINION :)

    I'm glad to hear that it works! I've always been somewhat skeptical of such rigs, from a reliability standpoint as well as a functionality standpoint. Sounds like the mechanics actually do play out, which is nice to know.

    How would that compair to the new Glock Gen 4's springs? those have the new double springs for that so it makes me wonder if Glock will be making the double spring for all their models? (just a thought)
