Introduction
The Taurus Model 66 is a reliable, well-built revolver known for its affordability and solid performance. It’s often recommended as a great choice for both beginners and seasoned shooters who want a dependable .357 Magnum. But no firearm is perfect—and the Model 66 is no exception.
Like any mechanical tool, it has its quirks. Whether you’re a first-time buyer or a long-time owner, understanding the common issues that can arise with the Taurus Model 66 can help you stay one step ahead and keep your revolver running smoothly. So, let’s take a deep dive into the six most common Taurus Model 66 problems and how to solve them.
Top 6 Taurus Model 66 Problems & Solutions
1. Shaking Cylinder Issue & Its Solution
One of the more frequently reported problems is a cylinder that feels loose or shakes slightly when locked into place. While it might not seem serious at first, a loose cylinder can affect timing and accuracy.
The cause? Over time, wear and tear on the cylinder stop, hand, or the center pin can lead to looseness.
Solution:
- First, inspect the cylinder stop notch and hand for wear. If you notice excessive play, replacement might be necessary.
- Tightening the yoke screw and ensuring it’s properly aligned can also reduce shake.
- If you’re unsure, a qualified gunsmith can measure the cylinder gap and adjust timing to ensure everything locks up tight.
Pro tip: Regular cleaning and lubrication can prevent premature wear on these parts.
2. Misfiring Problems & Its Solution
Few things are more frustrating than pulling the trigger and hearing a click instead of a bang. Misfires can happen occasionally with any revolver, but some Taurus 66 owners report more frequent misfires than expected.
What’s going on?
Misfires are usually related to light primer strikes, caused by a weak mainspring or an improperly adjusted hammer spring tension screw.
Solution:
- Check the firing pin for wear or damage.
- Make sure the hammer spring is properly tensioned—avoid over-loosening the tension screw when trying to reduce trigger pull.
- Consider replacing the factory spring with a quality aftermarket option like a Wolff spring kit for more consistent ignition.
Also, always make sure you’re using quality, factory-loaded ammo. Some cheaper rounds can contribute to misfires, regardless of firearm.
3. Hammer & Trigger Lock Issues & Its Solution
Some users have reported issues with the internal safety lock mechanism, which can unintentionally engage or cause the hammer and trigger to feel gritty or even seize up completely.
Why does this happen?
The Taurus internal safety lock system, while designed with safety in mind, can malfunction due to debris, corrosion, or faulty components.
Solution:
- Clean the internal components thoroughly, especially around the locking mechanism.
- Apply a small amount of gun oil to the lock mechanism to prevent rust or seizing.
- If the issue persists, consider having a gunsmith disable or remove the lock—though be aware this might void your warranty.
If your revolver locks up mid-shooting session, this might be the culprit.
4. Problems with Dry Firing & Its Solution
Dry firing—pulling the trigger without live ammo—is a common practice to improve trigger control. But with the Model 66, it comes with a caution sign.
The issue?
Repeated dry firing without snap caps can damage the firing pin or the firing pin hole.
Solution:
- Always use snap caps when dry firing to absorb the impact and protect the firing pin.
- If you’ve already damaged the firing pin, it may need replacement—a relatively inexpensive but important fix.
Note: This is not unique to the Model 66, but given the reports from users, it’s better to be cautious and protect your investment.
5. Problems with the Front Sight & Its Solution
Several Taurus 66 owners have experienced issues with the front sight either becoming loose or misaligned, affecting accuracy.
Why does this happen?
The front sight is pinned or screwed into place. Recoil and regular use can slowly work it loose.
Solution:
- Inspect the sight regularly to ensure it’s tight.
- If loose, apply a thread locker like Loctite to the screw (if it’s screw-mounted) and retighten.
- For pinned sights, you may need a gunsmith to re-stake or replace the pin securely.
And while you’re at it, consider upgrading to a fiber optic or night sight if you shoot in varying light conditions.
6. Issues with the Cylinder Dislocating & Its Solution
In rare cases, the cylinder may dislocate slightly during operation, leading to timing issues or even locking up the revolver.
What causes this?
This usually stems from a worn or misaligned yoke, weak crane lock, or improperly fitted center pin.
Solution:
- Have the yoke and crane inspected for proper alignment.
- Replacing a worn center pin or adding a shim can help secure the cylinder better.
- Ensure the ejector rod isn’t bent, as that can interfere with cylinder alignment too.
If your revolver locks up mid-operation, check for this issue—especially if it’s been heavily used.
