Work order — Walther P38

Taking the firearm apart for a job such as refinishing, and putting it back together to specification. Generated from the Pew-Takedown entry last updated 2026-10-29. Confidence: medium.

Shop difficulty: Tier 2 of 3

55 parts with a lot of small springs (about 14) and plungers in an open-topped frame and a slide holding firing pin, safety, signal pin and firing pin lock; Walther says detail work is for skilled craftsmen and reassembly only works hammer down. Evidence for Tier 3 (miserable-to-rebuild reports) was not found in reachable sources. 55 parts ('The Components of the Walther Pistol P 38' (p. 18) keyed to the exploded view (p. 17), items 1-55 in four units incl. magazine.). Pew-Takedown's rating, not the manufacturer's.

Bench time: strip ~30 min, rebuild ~50 min (estimate). Actual: strip ______ rebuild ______

Special tools:

• dovetail sight pusher (or brass drift and padded vise) — Removing and refitting dovetailed sights for coating

Watch for:

• Walther says further dismantling should be entrusted to skilled craftsmen. (both; Carl Walther (re-hosted on indaginibalistiche.it and pdf.textfiles.com))
• Reassembly can only be done with the hammer down; the ejector, release lever and trip lever must be pressed down for the slide to pass. (reassembly; Carl Walther (re-hosted on indaginibalistiche.it and pdf.textfiles.com))
• Frame pins can stand proud and catch the slide unless pushed flush. (reassembly; Legacy Collectibles (dealer guide))

1. Clear and make safe

1. Point the muzzle in a safe direction and keep your finger off the trigger.
2. Press the magazine release and remove the magazine.
3. Retract the slide fully to eject any chambered round and lock it open.
4. Visually inspect the chamber and magazine well, then physically feel the chamber to confirm it is empty.
   Warning: Look and feel. Both, every time.
5. Remove all live ammunition from the work area.

2. Disassemble

Field Strip

1. Complete the Clear and Make Safe procedure and let the slide forward.
2. Rotate the takedown lever on the left front of the frame downward about 90 degrees.
   Tip: It is a substantial lever and rotates positively. If it resists, check the slide is fully forward.
3. Pull the slide slightly rearward, lift the rear of the slide up, and ease the slide and barrel assembly forward off the frame.
   Warning: The two recoil springs, one on each side of the frame, are under tension.
4. Press the locking block plunger and separate the barrel and locking block from the slide.
5. Stop here for routine cleaning.

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.

No manufacturer statement of materials or finish is recorded. Identify each part's material before choosing prep and cure.

The manufacturer's full parts list (55 parts) is on the reference page.

4. Reassemble

Reassembly

1. Fit the barrel and locking block assembly into the slide and seat it fully forward.
2. Set the slide and barrel assembly onto the frame rails from the front and push it rearward until it seats.
3. Rotate the takedown lever back up to its locked position.
   Warning: Confirm the lever is fully up. A partially rotated lever lets the slide come off under recoil.
4. Rack the slide several times and perform the function check.

5. Torque

No manufacturer torque values are recorded for this firearm.

Notes: The manufacturer's documents give no torque value. They say: "Insert the conversion barrel (liner) into the barrel of the P 38, apply the spring washer and the lock nut, and tighten up with the aid of the ejector tool by applying the latter to the groove." (Walther Pistol P 38 instruction manual (English; Carl Walther, Ulm/Donau), PDF p. 21 (4 mm conversion unit))

Fit or check on rebuild

• Parts generation (P38 vs P1) and headspace on mixed guns — P1 and wartime parts differ; mixed guns need fitting and a headspace check
• 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.
• With the hammer down, press the trigger for a double-action hammer fall.
• Cock the hammer, operate the safety or decocker as fitted, and confirm the expected behaviour.
• Rack the slide and press the trigger for a single-action break.
• Hold the trigger back, rack the slide, release slowly and confirm the reset.
• Confirm the slide locks open on an empty magazine and the magazine drops free.
• With the hammer cocked, rotate the safety lever down. The hammer should fall safely with the firing pin blocked.
• Inspect the firing pin for cracks or chipping during every cleaning, particularly on wartime pistols.

If any check fails, the firearm is not safe to fire. Stop and see a licensed gunsmith.
