So in the beginning, we had the P99, which then spawned the PPQ and the Canik TP9 series (so we already know the TP9 and PPQ are very closely related).  Walther then came out with the PDP, which is an evolution of the PPQ.  So all of these pistols share the same ancestry... but to what extent are they compatible with each other?

I know this question is pretty vague, but since it's already well known that some parts work with others, like how the mags/frames can swap between the TP9 and PPQ M2, perhaps it'll be beneficial to keep a quick reference running list somewhere of parts that are cross compatible between any combination of these pistols.

Personally, I think it would be cool to just see a 5' PDP or TP9 slide on a Q5 Steel Frame lower.

Running list:

• Official list from Walther about PDP/PPQ parts compatibility: https://waltherarms.com/2021/01/14/walther-pdp-parts-compatibility/


• PPQ M2 mags will fit PDP Compact frames but not Full frames (see above)


• PDP 4' works with PPQ M2 2796066 Barrel (see above)


• PDP 5' works with PPQ M2 5' Polymer Frame Barrels (see above)


• Mags can be shared between TP9 and PPQ M2: https://www.youtube.com/watch?v=nhiEu95H6L0


• Frames can be shared between TP9 and PPQ (M2?): https://www.m4carbine.net/showthread.php?210373-Apparently-the-Canik-TP9-is-such-a-good-PPQ-clone


• TP9SF slide works on METE SFX frame, but not the other way around: https://www.youtube.com/watch?v=vUzCj9RFX_g comment by Lucas Blanchard


• P99, PPQ, TP9 (early-run?) sights are all cross compatible (thanks to user ftierson)


• Frames and slides from Canik Elite Combats, Canik Mete series, and the Canik Rival can all be swapped (thanks to user ceskaz)

If anyone else knows, or knows OF, any cross compatibility not listed here please post it below.  I'll add it to the list as soon as I see it.

I put Walther P99/PPQ night sights on my original series TP9s...

Just sayin'...

Frames and slides from Canik Elite Combats, Canik Mete series, and the Canik Rival can all be swapped, and fired. Just came from range after having done that with hundreds of rounds without a glitch.

Thanks for the input guys, logged back in after a while and put it up there.
