Frequently Asked Questions

What are the essential tools for disassembling a Smith & Wesson revolver?

The primary tool is a well-fitting screwdriver, ideally one hardened and shaped specifically for S&W screws. A parts cleaning brush, soft flannel rag, and suitable solvent like mineral spirits are also necessary for cleaning and maintenance.

How do you properly remove the side plate from a Smith & Wesson revolver?

To remove the side plate, place the firearm on a padded surface and firmly strike the side plate area to dislodge it. Never use a screwdriver to pry it off, as this can damage the stocks and frame.

What is endshake in a revolver and how can it be addressed?

Endshake is the forward and backward movement of the cylinder. Yoke endshake can sometimes be resolved by swapping the #1 and #2 yoke screws. Significant cylinder endshake typically requires factory repair.

Why should you not alter the strain screw on a Smith & Wesson revolver?

The strain screw controls the tension of the mainspring. Altering it to reduce trigger pull compromises the firearm's reliability, potentially leading to failures to fire or function correctly under various conditions.
