Walther PDP 4.5” Full Size with a 5” Ported Barrel, LOK Grips Weight Kit, and Home Made Thumb Rest

magnaport.com is the company that did the barrel porting for me. Very reasonable price. Great customer service and speed.

For the home made thumb rest. Here's the parts list -
Hex Socket Cap Head Screw Bolt Half Thread - https://a.aliexpress.com/_mOylWNC
Choose M3 thread size and the appropriate length you might want. Mine is 45mm.

M3 or M4 black washer on both sides of the frame in order to protect the frame from the friction of the screw and nuts. - https://a.co/d/7HKA5JY

Knurled Step Thumb Nuts - https://a.aliexpress.com/_mOFkc4I
Again choose M3 thread size and your fav color.

Note - This configuration's "thumb nut" is pretty long. It offers a large contact area but makes it almost impossible to put in a holster. If you want a shorter version, consider choosing a shorter screw, like 40mm (maybe), and a shorter thumb nut like this one - https://www.aliexpress.us/item/225183...

The holster that can accommodate the shorter version of the thumb rest is RHT - https://www.redhilltactical.com. The one I got is https://www.redhilltactical.com/Walth...
The configuration is as follows -
Walther Holster | Competition
Walther Gun Options: PDP 5"
Suppressor Length Barrel: yes- I have a suppressor length barrel
Lights options: TLR2 (+$25.00)
Attachment Options: None - Bladetech/Boss/Springer pattern
Holster Color Options: Black
Inside color of double layer: Police Blue
Adjustable Retention Type: black knobs (+$8.00)
Shooting Strong Hand: right hand

The reason why RHT's holster can accommodate the shorter thumb rest version is that there's gap space they created on the holster for the Springer Hanger. I can't guarantee that a different configuration would work though. The risk is yours.
