Model Dash Caliber Notes
Model 10 10-7 .38 Special Old style hand; verify dash number before ordering

This hand is specific to the Model 10-7 dash variant. Hand geometry and ratchet engagement dimensions can vary between dash numbers. Verify your revolver’s dash number (stamped on the frame under the cylinder crane) before ordering. Gunsmith fitting required.

Function

The hand operates in both single-action and double-action modes, engaging the cylinder ratchet to rotate the cylinder one chamber per trigger pull or hammer cock. Proper hand length and tip geometry are critical for correct cylinder timing — the cylinder must be fully locked before the hammer falls. A worn hand causes cylinder timing failures, skipped chambers, or dangerous barrel/cylinder misalignment.

Installation Note

Professional gunsmith installation required. Hand fitting is a precision operation — incorrect length or tip geometry will cause timing failures or cylinder binding. Do not attempt installation without proper tools and training.
