⚠️ MIM Parts Only: This trigger is compatible with MIM-equipped revolvers only. Verify your revolver uses MIM internal parts before ordering. MIM parts were introduced in the mid-1990s — generally dash numbers 6 and higher on most models.
Replacing a worn trigger restores proper double-action and single-action function and feel.
Installation Note
Disassembly and reassembly required. Some fitting by a qualified gunsmith may be necessary.
How to Identify Your S&W Model Number
Swing out the cylinder and check behind the yoke on the frame. Model numbers were introduced in 1957–58. If no model number is present, your revolver may pre-date that era — contact us with your serial number and we can help identify the correct part.
