Finally got out to test this recoil reduction setup. I installed in on my internally stock Glock 21. I first fired 20 round of blazer steel (or is it aluminum, whatever, its cheap) at a zombie target (only thing I had) at about 25 yards. 2 things came to light.
First, shooting a pistol accurately at 25 yards is really difficult. I thought i was a decent shot, and i am with 9mm... but this 45 is a whole different deal. Of the 20 rounds, maybe 5 hit the target at all with most of them being wildly off target all together.
Then I installed the recoil reduction setup and fired another 20 rounds. First, I think "recoil reduction" is the wrong description. My seat of the pants (so to speak) feeling was that the felt recoil was actually greater. HOWEVER... all other variable being equal, of the 20 rounds I fired WITH the reduction system installed ALL 20 hit the target and most were in the head area of the zombie dude I was shooting at. I took the same amount of time and was in the same position/stance/location... everything was the same.
I think a better description would be "accuracy improvement" system. Im very impressed and will be leaving this setup installed. Worth the 80 for sure. Thanks Zahal.
