S&W K Frame M&P 1st Model 4-Screw Trigger .265" Wide w/Hand .38 Colt – Part# MPC6

Smith & Wesson K Frame Military & Police 1st Model Trigger .265" Wide with Hand – 4-Screw, Old Style

A rare factory-original .265" wide trigger with hand for the earliest production K Frame revolvers. This part was sourced from a Military & Police 1st Model revolver (Serial# 3312) chambered in .38 Colt — one of the earliest S&W hand ejector revolvers ever produced. The .265" wide trigger provides a broader contact surface for a more comfortable and controlled double-action pull compared to the standard narrow trigger. The hand (cylinder rotating pawl) is included, making this a complete trigger assembly replacement. Correct-era trigger assemblies for these early 4-screw revolvers are extremely difficult to find.

Factory Replacement Quality

Genuine Smith & Wesson factory parts from the correct production era — same dimensions, same hand engagement geometry, same reliable trigger and cylinder timing. Correct-era parts for these early revolvers are increasingly scarce.

About the Hand

The hand (also called the pawl) rotates the cylinder one chamber with each trigger pull. Including it with the trigger ensures proper timing between the two parts — critical for safe and reliable function. On these early 4-screw revolvers, hand geometry differs from later K Frame production; trigger and hand fitting must always be performed by a qualified gunsmith.

About the M&P 1st Model

The Military & Police 1st Model (introduced circa 1899) was one of the first S&W swing-out cylinder revolvers and the direct ancestor of the legendary Model 10. Early production revolvers like Serial# 3312 predate the model number system by decades — if you're unsure whether this part fits your specific revolver, contact us with your serial number and we'll help confirm compatibility.
