Specifications

Model-specific safety

• A single-action revolver is loaded and unloaded one chamber at a time through the loading gate. There is no swing-out cylinder and no ejector star — index each chamber and check it individually.
• New Model Rugers have a transfer bar safety and are designed to be carried with all chambers loaded. Old Model Rugers (pre-1973, three screws in the frame) do not, and should be carried with an empty chamber under the hammer. Count the screws before you assume which you have.
• On New Models, opening the loading gate frees the cylinder to rotate. That is the intended design.
• Never remove, replace, or carry a loaded cylinder that is not installed in a revolver. The cartridges can fire if their primers are struck.

Under spring tension

• Base pin latch spring
• Mainspring
• Loading gate detent spring

Shop difficulty

Shop tier 1 Tier 1 — easy among revolvers, for the full job: strip to the parts that get coated and put it back together working. The smallest, simplest Ruger New Model single action here (47 pieces, fixed sights, coil springs); the only traps are the pawl plunger, the grip-frame springs and the loading gate.

Parts: 46 numbered parts (Wrangler list; the separate Super Wrangler list excluded (46 line items)), from Instruction Manual for Ruger Wrangler Single-Action Revolvers — Sturm, Ruger & Co., Inc., p. 29–30 ruger-docs.s3.amazonaws.com [1].

Bench time: about 20 min to strip, 35 min to rebuild (estimate). Estimated for an experienced tech: cylinder, ejector housing, base pin latch, grip frame, lockwork and gate out of the cylinder frame. Rebuild is longer for the pawl spring/plunger, the two springs between grip frame and frame, the loading gate and the transfer bar, then a function check. Fewest parts of the Ruger single actions.

Small parts: 11 pins, 4 springs, 6 detents or plungers (counted from the manufacturer's parts list (one per key number unless a quantity is given))

What comes off for coating

• Cylinder, ejector and base pin: base pin and cylinder, ejector housing with compressed ejector spring and rod, base pin latch, nut and spring — jaw-protected pliers
• Grip frame: grip panels, mainspring assembly (captured on its strut), grip frame / trigger guard screws and grip frame, trigger spring, trigger spring pivot and retaining pins, cylinder latch spring plunger and spring — pin or nail to capture the mainspring, fitted hollow-ground screwdrivers
• Cylinder frame: hammer pivot and hammer with pawl, pawl spring and plunger, trigger pivot, trigger and transfer bar, cylinder latch, loading gate and gate detent spring, firing pin, rebound spring and recoil plate cross pin (if the frame is stripped bare), front sight blade (fixed-sight model; rear notch is in the frame) — small pin punches

Special tools

• Fitted hollow-ground screwdrivers — Grip-frame, ejector housing and base pin latch screws
• Jaw-protected pliers — Holding the base pin latch nut while the latch is unscrewed (Ruger manual)
• Pin, nail or paper clip — Capturing the mainspring on its strut
• Small pin punches — Hammer, trigger and spring pivot pins

Known pain points

• Ruger asks for the job to be done with knowledge and care even though the mechanism has few parts. (both)
  Source: Instruction Manual for Ruger Wrangler Single-Action Revolvers — Sturm, Ruger & Co., Inc. ruger-docs.s3.amazonaws.com [1] — “Although the WRANGLER® revolver mechanism is composed of only a few parts, it is essential that the disassembly and reassembly operations be carried out with knowledge and care.”
• The base pin latch nut must be held with protected pliers while the latch is unscrewed, and its spring is easy to lose. (both)
  Source: Instruction Manual for Ruger Wrangler Single-Action Revolvers — Sturm, Ruger & Co., Inc. ruger-docs.s3.amazonaws.com [1] — “Do not lose the spring.”
• The pawl spring and plunger must go back in the right way round, plunger in and spring out. (reassembly)
  Owners report: Ruger New Vaquero Disassembly — Cowboy Action Shooting (CAS City) forum cascity.com [4] — “# 45 - Pawl Spring and Plunger assembly...make sure when you put the gun back together to get the plunger in and spring out.”
• The loading gate has to be held against the cylinder-latch disconnect while the gun goes back together. (reassembly)
  Owners report: Ruger Loading Gate Problem — Cowboy Action Shooting (CAS City) forum cascity.com [5] — “You really need three hands to make sure the Loading gate doesn't fall away from the cylinder disconnect for the bolt when you put it back together.”

Fit or check on rebuild

• Cylinder rotates and locks in each chamber, trigger returns, loading gate opens and closes normally — Ruger’s own post-reassembly check for the single actions.
  Source: Instruction Manual for Ruger New Model Blackhawk Single-Action Revolvers — Sturm, Ruger & Co., Inc. ruger-docs.s3.amazonaws.com [6] — “Check to be sure that the cylinder rotates and locks correctly, that the trigger returns in a positive manner when released, and that the loading gate opens and closes normally.”
• Transfer bar moves freely and the hammer cannot reach the firing pin with the trigger forward — A pinched transfer bar stops trigger return; this is the New Model safety.
  Source: Blackhawk Trigger Return Issue Help? — 24hourcampfire 24hourcampfire.com [7] — “The transfer bar is a prime candidate because it links directly to the trigger. Look hard at both sides of it, where it should travel freely in the frame.”
• Base pin fully seated and latched; base pin latch nut tight — A pin that is not home walks forward under recoil (entry commonIssues).
• Ejector housing screw re-threadlocked (non-permanent) — Ruger installs it with thread locker and asks for it to be reapplied.
  Source: Instruction Manual for Ruger Wrangler Single-Action Revolvers — Sturm, Ruger & Co., Inc. ruger-docs.s3.amazonaws.com [1] — “NOTE: The ejector housing screw is installed with a thread-locking adhesive.”

Procedures

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.

What the manufacturer does say: The manufacturer's documents give no torque value. They say: "NOTE: The ejector housing screw is installed with a thread-locking adhesive. If the screw is removed it is recommended that a non-permanent thread-locking adhesive be reapplied to the screw." (Instruction Manual for Ruger Wrangler Single-Action Revolvers, PDF p. 21)

Materials and factory finish

As stated by Sturm, Ruger & Co.. 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.

Parts list

Transcribed from the manufacturer's parts list (Instruction Manual for Ruger Wrangler Single-Action Revolvers — Sturm, Ruger & Co., Inc., p. 29–30 ruger-docs.s3.amazonaws.com [1]) — Wrangler; the manual's separate Super Wrangler list is not included. Exploded view on p. 31. Key numbers refer to the exploded view in that document.

Function check

• Verify every chamber is empty before each check.
• Cock the hammer and confirm the cylinder indexes and locks at each chamber.
• With the hammer cocked, confirm the cylinder is locked with minimal rotational play.
• Press the trigger and confirm a clean hammer fall.
• With the hammer down, press forward on the hammer. On a New Model the transfer bar should prevent the firing pin from being struck.
• Open the loading gate and confirm the cylinder rotates freely and the hammer cannot be cocked.
• Confirm the base pin is fully seated and latched.

Maintenance

Lubrication points

• Base pin
• Cylinder bore where it rides on the base pin
• Hammer and trigger pivots
• Loading gate pivot

Cleaning notes

Clean the base pin and the cylinder centre hole — fouling there is the usual reason a single-action cylinder drags.

Suggested inspection interval: roughly every 1000 rounds. This is a general guideline, not a manufacturer specification.
