How the Sear Spring System Works
The sear is part of the mechanism that holds the hammer in the cocked position until the trigger is pulled. The sear spring provides the controlled spring pressure needed to keep the sear engaged and to support consistent trigger and lock operation.
Sear Spring Applies Tension → Sear Engages Hammer → Trigger Releases Sear → Hammer Falls
When a spring becomes weak, bent, damaged, or inconsistent, the sear may not operate with the intended tension. Replacing both springs as a matched set helps maintain more consistent operation between the left and right locks.
Designed for Dependable Trigger Operation
Worn, weakened, or damaged sear springs can contribute to inconsistent trigger feel and unreliable sear engagement. Properly fitted performance springs can help restore smooth, predictable operation while maintaining the positive engagement required for safe function.
SliXprings Performance Sear Springs are precision manufactured to provide dependable spring tension and consistent operation in compatible TTN and Cimarron 1878 Coach Guns.
These springs are intended to replace worn or damaged factory components. They should not be used to compensate for improperly altered sears, unsafe engagement surfaces, damaged hammers, or other mechanical defects.
