I've got a PDP Compact and have been looking into these. Just wondering if anyone here has any experience with them and did it make a huge difference?

On the post above you said on how you put the 15lbs one but here you are saying the 17lbs. Which one are you using? I am thinking of getting one myself just debating between the 15 and 17

15lbs work great in my PDP with 115gr/124gr non P+ loadsOn the post above you said on how you put the 15lbs one but here you are saying the 17lbs. Which one are you using? I am thinking of getting one myself just debating between the 15 and 17
After I sold my Pro X PMM to Walther I built my own with my 4 and 5in PDPs and bought the PMM barrel and comp combo with the flat faced two chamber comp. I installed the ZRTS Ultra Mass recoil rod with a 15lb spring and it ran fine, but I could feel the slide clunk into battery, almost if something was trying to hold it up. I have a 17lb spring but I got the occasional stove pipe with it. Today I was headed to the range and decided to take out the ultra mass and shoot with the stock plastic guide spring. The clunk was gone which is great, but I also felt no difference whatsoever in felt recoil and performance of the gun. I’ll be sticking with the Walther guide rod.

Went back to the range on Saturday and put my Walther PDPD Pro X in the bag and shot Federal 115 and Blazer Brass 124 with out issues with the ZRT new Captured Guide Rod in the gun. Again zero issues. The guide rod might help a tiny bit but it is not night and day. The Surefire Turbo light on the gun helps way more as probably does the PMM Comp. Neat experiment but not needed.
For a comped gun I like my Sig P226 X-Five Legion a lot more. What a shout flat soft shooting laser of a gun. I normally do not sell my firearms but I might sell this Walther and pick up a SD version instead as I'd use that a lot more.

Sorry Doni... it is the 17lb spring in the captured ZRT Guide Rod.On the post above you said on how you put the 15lbs one but here you are saying the 17lbs. Which one are you using? I am thinking of getting one myself just debating between the 15 and 17

I’m assuming since Walther sell ZR rods on their website, that they are compatible n not prone to issues
Bear in mind that the weight difference between the two rods is 29 grams. A single 9mm 115 gr. cartridge weighs 12.2 grams. A loaded magazine of 15 rounds, as it's fired, changes the weight distribution of the pistol by 183 grams from full to empty. How much detectable difference do you think the rod can make?
I think the money is better spent on ammunition for practice.

What’s everyone’s thoughts on reducing the spring weight on a carry gun? Wouldn’t mind the reduced recoil but worry about reliability?
As far as I know, they generally recommend to use the V-spec guiderod for the PMM Walther PDP. But glad you are satified with the stock walther guiderod.

A lighter recoil spring doesn't automatically equate to less recoil, if I'm understand your post correctly.

Most of the upgraded captured recoil assemblies are SS & use a "Flat" spring coil vs a rounded one. So, better quality internals equate to better performance. All my stock Walther recoil assemblies are plastic, & their replacements are SS. I believe they create better shooting characteristics, concerning impulse recoil, muzzle flip, follow up shots, & cycling. Just my opinion.
There is two actions involved in the recoil actions. First gasses from burned propellant move slide in a backward direction and recoil spring absorbed that energy to make it smooth transition, end your gun ejector ejected empty shell away. Second is recoil spring unsprun and put the new round in the chamber, return to battery and you ready for the next shot. Systems like Sprinco or DPM utilize two or three different weights spring system that allows to absorb impact when gun is fired and provides more smooth action when gun slide returns to battery. That protects your weapon from slide getting slammed as it's return to battery. It's mostly insurance for your gun, but you need to choose right one that allows your gun to function properly and avoid mailfaction.

Interesting that Walther now has engineered a "Long Stroke Guide Rod" assembly for their P14, & P14K military models. ZR Tactical's long stroke guide rod assembly was emulated in Walthers design in some part, or theory. So, if Walther can see the need for upgraded recoil assemblies in some of their newer models, why shouldn't we as Walther owners upgrade our pistols as well. All my Walther pistols have upgraded captured recoil assemblies including ZR tactical, DPM, or Lakeline LLC. All benefiting each pistol with less impulse recoil, less muzzle flip, better cycling, & quicker spot on follow up shots. Personally, I try to keep the stock suggested spring weight with the upgraded captured recoil assemblies whenever possible. Also adding an adhesive pistol grip like talon, or others has helped me with handhold control as well.
There is some precedent. Apex was the first to produce a "performance" trigger for the PPQ.
Walther's DPT came later and seemingly leveraged what came before.
Vince provided an interesting bit of information in that Walther is modifying the PDP's slide to accommodate their long-stroke design.

The only mod needed to install the ZR Tactical Long Stroke Guide rod was removing the plastic plug off the slide that made most of their captured guide rod assemblies the same length. Other than that, what mods are you referring to?
I discussed this with some representatives from Walther and asked why the 5" Match Steel Frame does not come with the long-stroke guide rod out of the box. One of them then showed me his 5" Match SF and pointed out the marks that currently appear on the extractor. These marks are not problematic and are already known, but Walther believes this can be optimized. Therefore, newer versions of the PDP slides are milled slightly different to prevent these extractor marks when using the long-stroke system.
