Work order — Ruger MAX-9

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: high.

Shop difficulty: Tier 1 of 3

48 rows/53 pieces including two magazines and an optic cover, so about 40 working parts on a pinned frame insert; striker, extractor and blocker in the slide. Traps are small (takedown pin needs the plate down and the slide held 1/8 inch back; striker keeper cups). 48 parts (MAX-9 parts list incl. 10- and 12-round magazine assemblies and optic cover/screws (manual pp. 43-45); 48 rows.). Pew-Takedown's rating, not the manufacturer's.

Bench time: strip ~15 min, rebuild ~25 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:

• The takedown pin only lines up with the takedown plate pressed down and the slide held about 1/8 inch rearward. (both; Sturm, Ruger & Co., Inc.)
• Ruger says there are no user-serviceable parts below the field strip. (both; Sturm, Ruger & Co., Inc.)

Tools

• Small punch or paperclip — Pushing the takedown pin out through the slot on the right side of the frame.

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. With the safety in the FIRE position, pull the slide to the rear and lock it open by pushing upward on the slide stop.
   Warning: Keep your hand away from the muzzle.
4. Inspect the chamber and verify that it is empty.
   Warning: Look and feel. Both, every time. A trigger press is coming.
5. Remove all live ammunition from the work area.

2. Disassemble

Field Strip

1. Complete the Clear and Make Safe procedure.
2. Retract the slide slightly and release it. This disengages the slide stop and lets the slide run fully forward.
3. With the pistol pointed in a safe direction, pull the trigger to release tension on the striker.
   Warning: This is the trigger press this design requires. The chamber must already have been verified empty, with the magazine out and no ammunition nearby.
4. Using a finger or a soft tool, push the takedown plate down to expose the takedown pin.
5. Pull the slide rearward about 1/8 inch and hold it there, then insert a small punch or paperclip into the slot on the right side of the frame and push the takedown pin out the left side.
   Tip: The slide has to be held back or the pin cannot clear it.
6. Move the slide assembly forward and off the grip frame.
   Warning: If the slide will not move forward, you have re-cocked the striker while handling the slide. Repeat the trigger press in step 3 and try again.
7. Compress the recoil spring assembly slightly to disengage it from its seat against the barrel lug, and lift it out.
   Warning: Under spring tension.
8. Remove the barrel by moving it forward slightly, then down and back out of the slide.
9. Stop here.
   Warning: Ruger states there are no user-serviceable parts below this level. Further disassembly means contacting Ruger Customer Service.

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.

The manufacturer's full parts list (48 parts) is on the reference page.

4. Reassemble

Reassembly

1. Set the barrel into the inverted slide, seating it fully.
2. With the slide and barrel upside down, place the guide rod spring assembly into position so the rear end of the guide rod seats against the barrel lug.
3. Reinstall the slide onto the frame and move it to its closed position, as if the pistol were fully assembled.
   Warning: Never install the slide on the frame without the barrel and guide rod assembly already in the slide.
4. Make sure the takedown plate is pressed fully downward.
5. Pull the slide slightly rearward, about 1/8 inch, so the pin hole clears the slide, and insert the takedown pin into the frame insert until it is flush.
   Warning: Flush with the frame insert. A proud pin is not seated.
6. Move the takedown plate upward until it snaps into place.
   Warning: Do not fully rack the slide until the takedown pin is securely installed.
7. Perform the function check before the pistol goes back into service.

Fit or check on rebuild

• 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

• First be sure there is no ammunition in the chamber or magazine, and keep the pistol pointed in a safe direction.
• Slide: with the safety on FIRE and no magazine, pull the slide to the rear and let it run forward quickly, twice. It should move freely and close completely.
• Insert an empty magazine, pull the slide to the rear and release. The slide should be held open by the slide stop.
• Remove the magazine. The slide should remain open.
• Pull the slide fully to the rear and release. It should run freely forward to closed.
• Trigger: with no magazine and the safety on FIRE, cycle the slide to cock the striker.
• Move the safety to SAFE and attempt to pull the trigger. The trigger should move partially rearward and stop; the striker must not fall.
• Move the safety to FIRE. Pull the trigger and hold it back. The striker should fall with an audible click.
• Holding the trigger back, cycle the slide, then slowly release the trigger and feel the reset.
• Move the safety to SAFE and attempt to pull the trigger again. It should move partially rearward and stop.

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