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.

 

FAQ:

Q: What size do I choose?

A: We do not include the thread length in our length options– 4″ is compatible with a slide with a 4″ unthreaded barrel, or 4.6 factory threaded barrel. 4.5″ is compatible with a slide with a 4.5″ unthreaded barrel, or a 5.1″ factory threaded barrel.

 

Q: Can I buy just the micro or ultra comp?

A: Short answer, no. The barrel and comp are proprietary to one another. Due to the thread depth in the comp and the length of thread on the barrel, our barrel and comp can only be used together.

 

 

Size Guide:

Please order based off of slide length/ unthreaded barrel length.

3.5″ is compatible with the PDP F 3.5″.

4″ is compatible with a slide with a 4″ unthreaded barrel, or 4.6 factory threaded barrel.

4.5″ is compatible with a slide with a 4.5″ unthreaded barrel, or a 5.1″ factory threaded barrel.

5″ is compatible with a slide with a 5″ unthreaded barrel.

 

Flush Fit:

To achieve a flush fit look you will need a 4″ PDP slide and a 5″ full length frame paired with our 4″ ultra flat-faced barrel and comp.

A 4.5″ PDP slide and a 5″ full length frame with our 4.5″ micro barrel and comp will hang past the frame by approximately .100″.

Please note, a 3.5″ slide will only function on a 3.5″ frame, so not there are no flush fit options.

For flush fit, skip to minute six of the video below.
