- Carl Walther GmbH limits owner disassembly: Field strip, plus striker assembly, extractor and striker safety out of the slide, magazine disassembly, and backstrap, magazine-release and sight changes. No frame fire-control work.
- This work order is written for the Walther PPQ. It is reported to cover PPQ M1; PPQ M2; PPQ Q4 Steel Frame (with differences) — if the firearm on the bench is one of those, check the torque notes: values do not always carry over.
Shop difficulty: Tier 1 of 3
60 position numbers in Walther's PPQ M2 list, but assemblies, their sub-parts and alternate sights are all listed: about 45 working parts in a Glock-class layout. Walther documents the slide strip; the one awkward step is holding the safety plunger down while the extractor snaps in, with a 2 mm drift. 60 parts (Walther PPQ M2 9mm x 19 spare part list 279 58 33 Rev. a, 9 mm section (pp. 2-3), distinct position numbers incl. assemblies, sub-positions and alternate steel sights; .40, Navy and 5-inch rows omitte). Pew-Takedown's rating, not the manufacturer's.
Bench time: strip ~15 min, rebuild ~25 min (estimate). Actual: strip ______ rebuild ______
Special tools:
- 5/64" (2 mm) drift punch — Slide end cap and extractor plunger (per Walther)
- dovetail sight pusher (or brass drift and padded vise) — Removing and refitting dovetailed sights for coating
Watch for:
- Refitting the extractor needs a 5/64-inch (2 mm) drift on the extractor plunger, then the striker safety plunger held flush while the extractor is pressed home. (reassembly; Carl Walther / Walther Arms)
- The striker safety plunger spring has to be held in with oil and must reach the bottom of its blind hole. (reassembly; Carl Walther / Walther Arms)
1. Clear and make safe
- Point the muzzle in a safe direction and keep your finger off the trigger.
- Press the magazine release and remove the magazine.
- Retract the slide fully to eject any chambered round and lock it open.
- Visually inspect the chamber and magazine well, then physically feel the chamber to confirm it is empty.
Warning: Look and feel. Both, every time. - Remove all live ammunition from the work area.

Field Strip
- Complete the Clear and Make Safe procedure and leave the slide locked to the rear.
- Grip the takedown catch from above on both sides and press downwards.
Tip: Pressed down from above on both sides, not rotated. Confirmed for the PDP; the PPQ's catch works the same way, but see the sourcing note. - Release the slide stop and ease the slide forward off the frame.
- Lift the recoil spring assembly out of the inverted slide.
- Lift the barrel out of the slide.
3. Refinish
The components the procedures above separate. Coating, masking and cure are outside this database; follow your coating system's instructions. A part the manufacturer marks "factory fit" should not be swapped or reworked.

4. Reassemble

Reassembly
- Set the barrel into the inverted slide and seat it fully forward.
- Seat the recoil spring assembly into the cut in the barrel lug and press it down into the slide channel.
Tip: It seats in the lug cut, not on the barrel itself. - Set the slide onto the frame rails and push it rearward until it seats.
- Return the takedown catch to its locked position.
Warning: Confirm the takedown catch is fully returned before the pistol goes back into service. - Rack the slide several times and perform the function check.

Fit or check on rebuild
- Striker safety sits just below the feed rib — Walther's own check that its spring is seated
- Function check: trigger reset, sear/striker engagement, safeties — Standard post-reassembly check on any pistol whose fire-control parts were removed; a mis-seated spring shows up here, not on the bench
6. Function check

- Verify the pistol is unloaded with no magazine inserted before each check.
- Rack the slide and press the trigger. The striker should release cleanly.
- Hold the trigger to the rear, rack the slide, then release slowly and confirm the reset.
- Press the trigger again to confirm the striker releases.
- Confirm the slide locks open on an empty magazine and the magazine drops free.
If any check fails, the firearm is not safe to fire. Stop and see a licensed gunsmith.
