PMM Recoil Spring Recommendation:
Our ultra comp for the PDP was designed around the factory spring, but you may want to change it out. We recommend not going any lighter than 15 lbs.
We personally like and recommend the ZR Tactical Solutions PDP Captured Guide Rod. It is also compatible with the ZR Tactical Solutions PDP Ultra Mass Guide Rod.

The ultra comp on my PDP is one of the softest shooting guns I’ve ran. And the return to zero is immediate, so follow up shots are stupid fast.
Outside of performance Parker mountain deserves credit, this barrel is flawless in the machining and fit. Definitely a match grade barrel

I ran the single port comp on my PDP as soon as it came out. I was impatiently waiting for the Ultra to be released. I WAS NOT disappointed. The PDX is my favorite pistol and I love it. PMM makes an incredible product and I’m happy to support a small business!

I’ve wanted the Ultra Comp for all of my PDP’s ever since I put the single port on my first PDP. The single port was smooth. Since I already had the Ultra Comp for my Sig P320, I always thought the Ultra Comp would put the PDP over the top…and my guess was right! I love the flat face, with a 4″ slide, sitting on top of my 5″ frame. It it sooooo smooth and when reacquiring the target, my sight barely leaves the window (when shooting with red dots). This design just flat out works! I even bought the Glock Ultra Comp version (instead of the radian), because it just works better…and a better value!

Parker Mountain Machine (PMM) Review – PDP Double Comp Barrel Combo
I run the PMM double comp barrel combo on my Walther PDP Pro X FS, and it’s hands down my favorite handgun setup. PMM’s craftsmanship and performance are unmatched, making their products a staple in our arsenal at Mantis Strategic Defense. We run their barrels and compensator combos on both our Glock and Walther platforms, and I’ve recently added their +4 mag base pads to the mix for both platforms as well. Everything they produce is top-tier.
What really sets PMM apart, though, is their communication and customer service. They go beyond being just a company—they make you feel like a valued friend. Whether it’s answering questions, helping you try out gear, or just hanging out at events like Ohio Range Day, PMM is always approachable, knowledgeable, and willing to help.
Our company has a lot of respect for PMM, and we actively recommend their products to our clients. You’ll always find something from PMM with us on the range, and we’re excited to see this smaller company continue to grow and dominate the industry. They’ve earned our trust and loyalty. Highly recommend! 🤙🏼

I purchased the 4” Ultra Barrel and Comp Combo for my poly PDP. Got a chance to run it during a class and loved it. I will definitely pickup another combo for a backup setup.
