Mainspring Vise
Novice gun owners may try to disassemble a fine lock using a Channel Lock® or Vice-Grip® pliers, but every experienced gunsmith knows the value of our mainspring vise.

Avoid scratching your mainspring. Scratches form stress marks, eventually causing breakage.

Draw the lock to half cock, slip on the spring vise, gently tighten the screw, then gently lower the hammer. Never compress the spring past full cock!

Our mainspring vise costs less than the first replacement mainspring damaged by pliers. Antique locks deserve this care.
