Work order — Stoeger Coach Gun

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

65 listed parts (80 pieces) in a boxlock side-by-side: two hammers on hammer impeller springs, two sears and springs, cocking levers, a top-lever lock spring and a single-trigger equaliser, all on cross pins inside the frame. Strong springs must be controlled and the hammers and sears go back as pairs, but nothing is timed. 80 parts (Complete gun, single trigger extractor model: barrel, forearm, frame and stock assemblies; 65 line items). Pew-Takedown's rating, not the manufacturer's.

Bench time: strip ~50 min, rebuild ~75 min (estimate). Actual: strip ______ rebuild ______

Special tools:

• Firing pin nut spanner — Firing pin fastening nuts
• Punch set incl. drift for the trunnion pin — Hammer/sear and lever pins

Watch for:

• Stoeger does not recommend disassembly beyond the owner's manual except for repair; it is a close-tolerance action and lock work should go to a gunsmith. (both; Stoeger Industries (Benelli USA))

1. Clear and make safe

1. Point the muzzle in a safe direction and keep your finger off the triggers.
2. Push the top lever to the side to release the barrels, and open the action, supporting the barrels as they drop.
3. Remove any shells from both chambers, or let the ejectors throw them clear.
4. Look through both barrels from the breech end and confirm both chambers are empty and both bores are clear.
   Warning: Both chambers. Both bores. An obstruction in a shotgun bore will destroy the barrel.
5. Leave the action open and remove all live ammunition from the work area.

2. Disassemble

Field Strip

1. Complete the Clear and Make Safe procedure, leaving the action open.
2. Release the forend catch and lift the forend off the barrels.
3. With the forend removed, pivot the barrels further open and lift them off the hinge pin.
   Warning: Support the barrels. They are the heaviest single piece and they will fall if you let them.
4. Clean both bores from the breech end, the chambers, the breech face, and the hinge pin and hook surfaces.
5. Stop here. The lockwork inside the action body is gunsmith territory.
   Warning: Break-action lockwork uses strong springs and fitted parts. Leave it alone.

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.

4. Reassemble

Reassembly

1. Engage the barrel hook onto the hinge pin and pivot the barrels closed onto the action face.
2. Fit the forend onto the barrels and engage its catch.
   Warning: Confirm the forend is latched.
3. Close the action fully until the top lever returns toward centre.
   Warning: Confirm the action locks shut. A break-action that does not lock is dangerous.
4. Perform the function check.

5. Torque

Notes: The manufacturer's documents give no torque value. They say: "Over tightening of stock bolt may adversely affect proper functioning of gun." (Owner's Manual, Coach Gun Side by Side Shotgun, Single Trigger Extractor Model (and Double Defense), PDF p. 9)

Fit or check on rebuild

• Top-lever centring and lock-up — The lever may not centre on a new gun by design; it must lock fully and the barrels close without force.
• Function check: safety, trigger/sear release, disconnector and feeding with dummy rounds — Standard after any detail strip; a mis-assembled sear or disconnector can double or fail to fire.

6. Function check

• Verify both chambers are empty before each check.
• Close the action and confirm it locks shut with the top lever returning toward centre.
• Engage the safety and press each trigger in turn. Neither hammer should fall.
• Disengage the safety and press each trigger. Each should release its hammer.
• On a single-trigger gun, confirm the barrel selector works and that the trigger switches barrels after the first release.
• Open the action and confirm the extractors or ejectors lift or throw snap caps as expected.
• Confirm the forend is securely latched.

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