The Model 10 is a medium-frame 6-shot revolver chambered in .38 Special, originally known as the Military & Police (M&P) model. The thumb piece is the lever on the left side of the frame that releases the cylinder latch, allowing the cylinder to swing out for loading and unloading. This is the old style design used in earlier production Model 10 revolvers.

About the K Frame Model 10:
The K Frame is Smith & Wesson's medium-sized revolver frame, known for its versatility and balance. The Model 10 has been in continuous production since 1899 (originally as the Hand Ejector M&P) and has served countless law enforcement agencies, military units, and civilian shooters worldwide. It remains one of the most reliable and proven revolver designs ever made.

Used parts offer an economical solution for repairs and restorations while maintaining OEM quality and fit.

Installation:
Professional gunsmith installation is recommended for proper fitting and function. The thumb piece and nut require proper installation to ensure reliable cylinder release operation. Knowledge of Smith & Wesson revolver mechanisms is helpful for installation.
