Unlike its blue counterpart, this nickel M-29 8-3/8" preferred hunting to silhouette competition, with barnyard duty occasionally on the menu. Built around 1980, nickel gun is much newer than the blue .44 Mag in LXVI, LXVII, and LXVIII. Grip shown is Pachmayr Gripper.
Nickel 29 finds happiness with original Target Trigger. David finds serrated wide Target, smooth medium Combat, and serrated narrow triggers perform equally well on long barrel N-frames. While Target Trigger and Target Hammer work perfectly well on the .44 N-frame, proportions due not suit well on .38-scale K-frame.
Target Trigger in single action mode.
Basic cylinder assembly parts, rows L-to-R:
* Top row: extractor; center pin spring (small spring); center pin bushing.
* Middle: center pin; ejector rod.
* Bottom row: cylinder; extractor spring; yoke.
Gas sealing of S&W is so effective that disassembly is seldom necessary. Motor oil and moly-disulfide grease prolong service life. Gummy oils such as WD-40 should be avoided, except for protecting outside. Synthetic motor oil resists stiffening in the North Country. Synthetic diesel oil and transmission fluid have carbon-cutting properties, good for cylinder axel on yoke.
Ejector rod screws to extractor star with left-hand (counter-clockwise) thread. Tightening and loosening must be done with cylinder on yoke, and with fired cases in cylinder (to keep strain off keyway and two pins that align extractor in cylinder). Knurled end of ejector rod is padded with heavy leather or lead flashing. Since cylinder slides off yoke once assembly is removed from revolver, lubrication does not normally require unscrewing ejector from extractor star.
Over time, lube holds wear signature to a minimum. Moly grease in standing breech. Motor oil is fine.
