We don't have one in our company reference collection and I can't find one of these locally to measure.
If anyone here has a Walther PPQ 9mm with the factory 1/2-28 threaded barrel and a set of calipers, would you be willing to help a brother out and take a few measurements and share them with me?
Have a look at the image below. There are the features I'd like to have measured.
Many thanks!
