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.
