Function:

The hand spring provides the tension necessary to push the hand against the cylinder ratchet during trigger pull, ensuring the cylinder rotates properly and locks into position for each shot. A worn or broken hand spring can cause cylinder timing issues or failure to rotate.

New Style vs. Old Style:

This new-style MIM hand spring uses a push-in installation method rather than being pinned in place like older designs. Verify your revolver uses the new-style design before ordering. Contact us if you’re unsure which style you need.

Installation Note: Disassembly of the revolver’s internal mechanism is required. Professional installation by a qualified gunsmith is recommended.
