Charter Arms Undercover

Low-confidence entry This entry has not been verified against an authoritative source. Treat every step as a starting point to check against your manufacturer's manual, not as instruction to follow. Rated low confidence for the disassembly section. The clearing procedure and the function check are reliable, and the important structural point — a one-piece frame with no sideplate, so owner work stops at the cylinder — is well established. The exact cylinder release procedure varies across Charter production and has not been verified against a factory manual. Use the manual for your revolver.
Before you begin Verify this firearm is unloaded. Remove the magazine or empty the cylinder or tube, lock the action open, and check the chamber both by sight and by touch. Keep the muzzle in a safe direction and remove all live ammunition from your work area.

Model-specific safety

Trigger press: not confirmed either way This entry records that no trigger press is needed to disassemble, but that has not been checked against the manufacturer's manual — no manual is cited here yet. Several entries in this database were found asserting exactly this and turning out to be wrong. Treat the takedown as if a trigger press may be required: confirm the chamber is empty before you begin, and check your own manual.

Shop difficulty

Shop tier 2 Tier 2 — moderate among revolvers, for the full job: strip to the parts that get coated and put it back together working. Small 5-shot DA with a one-piece frame and no sideplate, so the lockwork comes out through the bottom with the trigger, hand and transfer-bar safety as a group; fewer loose parts than a S&W, but the procedure differs from every other DA and Charter treats the lockwork as not owner-serviceable. Moderate, low confidence.

No sourced part count yet.

Bench time: about 30 min to strip, 50 min to rebuild (estimate). Estimated: grips, cylinder/crane, trigger group and hammer out through the bottom of the one-piece frame, ejector parts and sights. Rebuild dominated by refitting hand, transfer bar and springs through the bottom and a timing check.

Procedures

Clear and Make Safe

Clear & Make Safe
  1. Point the muzzle in a safe direction and keep your finger off the trigger.
  2. Push the cylinder release forward and swing the cylinder out.
  3. Press the ejector rod firmly to eject all cartridges or cases.
    Removed at this step: Cartridges or cases
  4. Look through every chamber, one at a time, and confirm each is empty.
    WarningEvery chamber, counted.
  5. Confirm the bore is clear and remove all live ammunition from the work area.

Field Strip — Cylinder Removal

Field Strip

Owner-level work on a Charter stops at the cylinder. There is no sideplate.

  1. Complete the Clear and Make Safe procedure and leave the cylinder open.
  2. Following the procedure in the manual for your revolver, release and withdraw the cylinder and crane assembly from the frame.
    WarningCharter cylinder retention differs from the S&W yoke screw. Do not apply an S&W procedure to it.
    Removed at this step: Cylinder and crane assembly
  3. Clean the chambers, bore, cylinder face, forcing cone, and crane bearing surfaces.
  4. Stop here. The one-piece frame has no sideplate and the lockwork is not owner-serviceable.
    WarningIf the revolver is not functioning correctly, send it to the manufacturer or a gunsmith.

Reassembly

Reassembly
  1. Reinstall the cylinder and crane assembly into the frame following the manual for your revolver.
  2. Close the cylinder gently by hand and confirm it latches.
    WarningNever flick it closed.
  3. Perform the function check.

Torque specifications

No sourced torque values from the manufacturer are recorded for this firearm. Where a fastener has a specified torque — action screws, scope bases, muzzle devices, barrel nuts — get it from the manufacturer or a gunsmith rather than estimating it.

Materials and factory finish

As stated by Charter Arms. Prep, masking and cure depend on these; a polymer or aluminium part, a nitrided or anodised finish, and a blued steel part are each a different job. Variants with other finishes may exist — check the maker's page for the exact SKU on the bench.

Function check

After every reassemblyPerform these checks on a verified-unloaded firearm. If any check fails, the firearm is not safe to fire — stop and see a licensed gunsmith.

Maintenance

Lubrication points

Cleaning notes

Clean the chambers, cylinder face, and forcing cone. Keep lubrication sparing — revolver lockwork does not want to be wet.

Suggested inspection interval: roughly every 1500 rounds. This is a general guideline, not a manufacturer specification.
