I noticed less muzzle rise from the DPM recoil reduction system as opposed to the OEM spring. Regardless, you shot the majority of your rounds low. I think you sacrificed accuracy for speed, hence you shot low?
From this test, to me it looks like the factory spring won this shootout. The only way to make it more fair is do the test on 2 separate days. 1 day cold shots with the factory spring. The next day cold shots with the replacement spring. Honestly, I like to use all bone stock parts and get as good as I can with it. Sometimes when you start trying to tune a gun, you can go down a deep rabbit hole and sometimes make things worse. Not to mention all the extra money you spend. I’d rather buy ammo with that money. I figure the boys at Walther know more about designing and engineering a gun a lot better than I do. That’s just me though.
All comp shooters I know of are replacing there recoil springs. As have several guys I know changed out theirs, it makes a difference and you don’t have to worry about deformation on a plastic guide rod. Scott Jalinski one of the designer and influencers of the pdp says these guns are over sprung also.
Zr tactical 15lb spring and guide rod on so much better than the DPM, my opinion, zr tactical dose a very good job keeping muzzle down on the pdp, I tested
You know what works for keeping the muzzle down on a PDP much better than wasting money on recoil spring replacement? A proper and solid grip. That’s what worked for me. The PDP revealed what I was doing wrong with my grip. I fixed my grip and now it runs as flat or flatter than any of my other pistols.
@TheAxe4Ever The PDP is a complete letdown for me. You should not be focusing that much on proper grip just to keep the muzzle down on a gun. It's just a range toy for me. It's not a gun I'd feel comfortable with to defend my life in a panic situation, if I need to make sure everything is correct to hit target. My glock 45, my sig p226, my APX A1, the only thing I think about with those firearms is keeping the dot on the target. The dam pdp is like a raging bull you're trying to tame. My 45s and 40s have less perceived recoil then my pdp compact. If ZR tactical recoil spring can help, I'm with it...
@@r1sabotagethe return to zero matters a lot more then “FELT recoil” and the pdp excels in that area. It feels like it kicks more than a lot of other guns yet I can shoot it faster than any other polymer gun out there( there’s a couple exceptions which don’t fit the carry category for me)
Thumb up after just 1:30 min for giving your test setup some serious thought. However, you should have done the test in two days instead, one for each spring. With warmup and shooting for each spring and then doing each drill twice for each spring. I know that would be a lot more involved but the way you did it you have too many shooter related factors that sadly make the result almost useless.
Like most weapons modification, people change things out not because of an issue, but because they saw someone change theirs out. I have a PDP Pro Compact and was just on ZR Tactical website to purchase a 13 lbs captured guide rod. The only reason I was looking is because I saw someone on RU-vid with their factory guiderod cracked at the end. I shoot every other weekend or so but only 200 rounds so I doubt mine will crack with that amount our rounds if I do it the entire year. I haven't paid yet, its just in my shopping cart as I look at more videos to see why people are changing theirs out...Hmmmmm 🙂
@@turbo15100 I would say the non captured adjustable version is a better fit for most people on the PDP. It's definitely noticable and worth it given the PDP snap. It's more noticeable the more you push it, but definitely more noticeable on the adjustable version.
Yes there is a difference in felt recoil. You can tell when it's installed that it recoils less but for me it did not improve "MY" performance during this shooting session. Although you can't count that because my shooting sucks.
@turbo15100 how did the new set up effect racking the slide? I ask because i purchased a pdp-f 4" so a lady friend could shoot it when she visits. I'd like to mitigate muzzle rise but not lose the "easier" racking ability. i also understad that grip is a huge factor and honestly will admit that i am not the person who has enough knowledge to be teaching that. Thank you.
I can't really say I noticed a difference in slide racking but that operation is really all technique. I would suggest to her if she is right handed of course grab the slide with the left hand and the grip with the right and grip firmly on both then with a quick motion move both arms inward at the same time to chamber a round instead of trying to hold the pistol in one position while moving the slide with the other hand which is way for difficult for someone with less muscle strenght.@@robertkwiatkoski1292
