1. Cylinder Shaking:

There is a known cylinder problem with the Taurus model 66. The cylinder may move from side to side. The condition is known to worsen with time.

The issue mostly arises if you use .357 caliber bullets. The cylinder shakes less with the .38 mag, however.

The major cause is that the Taurus model 66’s medium-sized frame must endure significant stress due to the .357 bullets’ high impact.

The Fix:

If you observe any cylinder shaking, you need to fix the revolver as quickly as you can. Even though 0.001 inches of shake might seem typical, it might progressively get worse.

Shims can be installed to address the problem momentarily. However, you ought to get the gun to the gunsmith right away.

You should also use the Taurus model 66 to fire the .357 less and the .38 more to avoid this problem.

2. Cylinder Locking While Dry Firing:

If you are dry shooting with the Taurus model 66, the cylinder may lock up.  Along with the cylinder, the hammer will also get jammed.

This problem develops when the side plate’s screw comes free. The screw is located at the top of the trigger.

The Fix:

Be sure to check the screw on the side plate if your hammer and cylinder are becoming locked up.

If the screw is loose (Fig 1), tighten it up using a screwdriver. The issue should be resolved straight away.

3. Dislocated Cylinder:

If you eject the cylinder, it can slip back onto the yoke. It will eventually go all the way to the extractor star as a result.

The cylinder’s base may rest up against the grips. The front portion of the cylinder can be pushed. It will release itself and re-slide onto the yoke.

The Fix:

This problem will occur if the retaining bushing of the cylinder sustains damage. When removing and reassembling the cylinder, the retaining bushing may be harmed.

You may check the bushing by removing the cylinder from the yoke. Get the revolver to a gunsmith if the area is damaged. If the damage was caused by the user, Taurus can decline to fix it under warranty.

4. Trigger and Hammer Locking:

The trigger and the hammer of the Taurus model 66 can get locked up. This issue may occur due to a fault in the transfer bar.

Also, if the user fails to reassemble the gun correctly after disassembling it, the hammer and the trigger will be seized.

The Fix:

You should replace the transfer bar if it has been damaged or faulty from manufacturing. Taurus can send a replacement or you can send the gun to get the transfer bar replaced.

If the transfer bar gets stuck while assembling the Taurus model 66, you should follow the manual for properly reassembling it. Take a look at this video for a visual demonstration.

5. Short Front Sight:

Some Taurus type 66s may have a smaller front sight than other 66s.  A manufacturing flaw creates this problem.

Due to this condition, aiming and firing may become challenging. Although the rear sight is adjustable and the front sight is fixed, the rear sight’s movement is insufficient to tackle this issue.

The Fix:

Since this is a manufactured defect, you should submit the firearm to Taurus. They will repair the issue without charging you.

Considering the front sight is fixed, neither gun shops nor gunsmiths can give you a replacement. It will thus be advisable to send the revolver to the company.

You can also take off the fixed sight and install a new one if you have expertise in handling and modifying guns.
