At Gunblast.com, we are constantly receiving
products for review, some of which are junk, while others prove
to be quite useful. Some are good products that simply do not
mesh with our interests, while others are good products that
would be of interest to at least some of our readers. The
product reviewed here fits nicely into the latter category.
A few weeks ago, I was contacted by Mr. Dimitrios
Mantas of DPM Systems Technologies, asking if I might
be interested in looking at a new recoil spring system for Glock
pistols. The Glock is one of the most popular auto pistols in
the world, so I judged this might be of interest to many of our
readers. Among other things, Mr. Mantas claimed that his spring
system reduced felt recoil, improved reliability, enabled faster
repeat shots, aided weapon control, and worked as a slide
buffer. This piqued my interest, and being that Mr. Mantas was
in the country of Greece, he instructed me to contact his
distributor for the western hemisphere, Dead Bang Guns and
Automatics, which I did.
DPM manufactures two systems for the Glock; one
mechanical, and another that adds a magnetic dampener to the
system. The mechanical system consists of a multi-spring setup
on a stainless guide rod, and adds no attachments to the outside
of the pistol, and that is the unit that was sent to me for
testing. The unit supplied fits the Glock models 19, 23, and 32.
That is Glock's midsize frame, and one that is quite popular
The unit supplied to me came with two different
springs to fit outside the guide rod. The other springs are
captive within the rod. I installed the spring/rod unit
into my well-used Glock 19 using what appeared to be the
stronger of the two springs. Cycling the slide by hand, one can
definitely feel the added resistance near the end of the
slide’s rearward travel. One cannot "slam" the slide
all the way to the rear with the DPM unit. It is as if there is
a buffer between the slide and frame. Cycling the slide normally
to chamber a cartridge from the magazine is not any harder to do
than with the stock spring system.
While by no means a scientific test, I proceeded
to shoot the Model 19 with a variety of Plus P and Plus P Plus
ammunition; mostly Cor-Bon hollowpoints, along with some
of their PowRBall ammo. I
cannot prove that the DPM system improves reliability, as this
Model 19 has never malfunctioned before, but it is still one
hundred percent reliable with the DPM recoil system installed.
While the 9mm Luger cartridge is not a hard kicker to begin
with, I could feel that the slide was not slamming into the
frame as it cycled, as it had before with hot ammo. While this
is only a subjective view, the gun feels much smoother in
operation now than it did before. Quick double-taps are very
controllable with the DPM system installed. The Model 19 now
feels more controllable, smoother, and seems to operate
"slicker’ than it did with the stock system.
While my experience with the DPM system is
limited to use with this one Model 19, I am so far impressed.
Hopefully, I can try their recoil system with other Glock models
soon. I would have liked to have tried it with the Model
20 that I recently reviewed, as with some loads it
bucked pretty hard. Also, their magneto-mechanical system
seems interesting, but it does attach to the accessory rail of a
Glock pistol, and would need a holster that is cut to
accommodate the unit. I think that the mechanical system
tested here should prove useful to all Glock shooters,
particularly competitors and law enforcement personnel.
It has no bad characteristics, and the benefits of lighter felt
recoil, smoother performance, faster repeat shots, and reduced
slide battering should appeal to all Glock users. It sells
for just 69 bucks, US, and is money well spent.
