This section explores frequently reported problems with the Smith & Wesson 648 revolver. We'll address the issues in detail, explaining possible root causes and offering practical solutions. Remember, always prioritize safety when handling firearms.
1. Cylinder Timing Problems
- Symptoms: The cylinder may not align properly with the barrel, causing misfires or dangerous situations. You may notice a noticeable gap or misalignment.
- Causes: Wear and tear on the cylinder, hand, or ratchet are the most common culprits. Improper maintenance, or using excessive force, can also contribute.
- Solutions: Minor timing issues might be resolved by adjusting the timing screw (if you are experienced in gunsmithing). For more serious problems, a qualified gunsmith should inspect and repair the revolver. Never attempt complex repairs yourself unless you have the necessary expertise and tools.
2. Double Action Issues
- Symptoms: The revolver's double action mechanism might feel stiff, gritty, or even fail to fully cycle. This can lead to misfires or delays in firing.

- Solutions: Thoroughly clean and lubricate the revolver's internal components, paying special attention to the double-action mechanism. If the problem persists after cleaning and lubrication, a professional gunsmith might be needed.
3. Trigger Issues
- Symptoms: A heavy, gritty, or inconsistent trigger pull can affect accuracy and shooting comfort. In extreme cases, the trigger may fail to function properly.
- Causes: Similar to double action issues, dirt, grime, and lack of lubrication can affect trigger performance. Wear and tear on the trigger components can also occur.
- Solutions: Start with a thorough cleaning and lubrication of the trigger group. A competent gunsmith can address more complex trigger problems involving adjustments or part replacement.
