Top 6 Taurus Model 66 Problems & Solutions

1. Shaking Cylinder Issue

In my hands-on experience with the Taurus Model 66, I quickly noticed an unsettling problem: the cylinder’s movement from side to side. 

This issue became more apparent as I continued to use the .357 caliber bullets. With .38 mags, the shaking was less pronounced, but it was still there. I realized that the medium-sized frame of the Taurus model 66 has to endure significant stress from the high impact of the .357 bullets, causing the shaking. 

Over time, I observed that this condition worsened, making it urgent to address.


Facing the cylinder shaking issue, I sought a solution. My immediate fix was installing shims, which did help temporarily. 

However, it wasn’t a long-term solution. I then decided to get the gun to a gunsmith without delay, as professional intervention was needed. To avoid this problem in the future, I also started using the .38 caliber more and the .357 less. 

It was a valuable lesson in understanding the firearm’s capabilities and the importance of prompt action when a problem arises. Trust us; it’s better to get it fixed quickly rather than let a minor issue turn into a major one!

2. Misfiring Problems

While testing the Taurus Model 66, I found another problem that was hard to ignore. The gun seemed to misfire or not fire at all quite frequently. It’s an issue that can be particularly concerning, especially when you rely on the firearm for critical situations. 

The consistency of this problem pointed towards a technical issue, not just a random occurrence. It wasn’t just us; I’ve seen other users online expressing similar concerns. 

Misfiring can lead to unsafe situations, so I knew I had to investigate and resolve it.


My suspicion quickly fell on the firing pin as I delved into the misfiring issue. It appeared that the firing pin wasn’t hitting the primer hard enough. 

After a thorough examination, I decided to change the firing pin. This solution proved effective, and the misfires were significantly reduced. 

If you’re experiencing similar problems with your Taurus Model 66, I recommend examining the firing pin. Sometimes, a simple change like this can make all the difference. And remember, safety first! If you’re not comfortable doing this yourself, don’t hesitate to consult a professional gunsmith.

3. Hammer & Trigger Lock Issues

During my comprehensive review of the Taurus Model 66, I stumbled upon another frustrating problem. The hammer and the trigger of the gun tended to get locked up. This wasn’t a one-time fluke; it happened more than once and seemed to be an underlying issue with the firearm. I noticed two main reasons for this issue.

First, there could be a fault in the transfer bar, and second, incorrect reassembling of the gun after disassembling it. 

Both situations could cause the hammer and the trigger to seize up, and I found myself dealing with this issue first-hand.


The fix for this problem depended on the cause. If the issue was with a damaged or faulty transfer bar, the solution was to replace it. Taurus can send a replacement, or you could get the transfer bar replaced by a professional. 

I tried this, and it worked. If the problem occurred due to improper reassembling, carefully following the manual for proper reassembly did the trick. I’ve been through it, and these solutions were effective for us. 

But don’t take my word for it; if you experience similar issues, follow these steps, and you should find yourself back on track. Always prioritize safety and consult a professional if needed!

4. Problems with Dry Firing

While dry-fired the Taurus Model 66, I experienced an alarming issue where the cylinder and the hammer would jam. Initially, I was puzzled by this unexpected behavior, but upon closer inspection, I found that the problem was linked to a specific part of the gun. 

The screw located at the top of the trigger on the side plate had come loose. This small detail had a significant impact on the firearm’s functionality, and I found myself dealing with this problem more than once during my testing.


The solution was surprisingly simple. All I needed to do was tighten the loose screw on the side plate, and the issue was resolved straight away. 

I used a standard screwdriver for this, and it worked like a charm. If you ever find your Taurus Model 66’s hammer and cylinder getting locked up, especially during dry firing, check this particular screw. 

It might seem like a minor detail, but it can make all the difference in the performance of your firearm. Trust us, i’ve been there, and a quick fix like this can save you a lot of frustration!

5. Problems with the Front Sight

In my hands-on experience with the Taurus Model 66, I encountered a problem that initially seemed minor but turned out to be a real challenge. 

Some of the 66s I tested had a smaller front sight, which I identified as a manufacturing flaw. This small difference seriously affected my ability to aim and fire accurately. 

Though adjustable, the rear sight didn’t offer enough movement to compensate for the issue with the front sight. I found myself struggling to align my shots properly, and I knew I had to find a solution to this problem.


Upon discovering this defect, I realized the best course of action would be to send the firearm to Taurus. Since it was a manufacturing flaw, they were willing to repair the issue without charging us. 

Though some might consider removing the fixed sight and installing a new one, sending the revolver to the company was the most straightforward and safest solution. 

I know from experience that handling and modifying guns requires expertise, so I urge anyone facing this issue to consult the manufacturer. 

6. Issues with the Cylinder Dislocating

I noticed something quite odd while in the field with the Taurus Model 66. When I ejected the cylinder, it would slip back onto the yoke, eventually going all the way to the extractor star. 

The cylinder’s base would rest up against the grips, a situation that left me scratching my heads. By pushing the front portion of the cylinder, it would release itself and re-slide onto the yoke, but the fact that this was happening at all concerned us. 

I knew I had to investigate this problem and find a solution.


My research and hands-on testing led me to discover that this problem occurred if the retaining bushing of the cylinder sustained damage. 

In removing and reassembling the cylinder, the retaining bushing might be harmed. I checked the bushing by removing the cylinder from the yoke, and in my case, I had to get the revolver to a gunsmith as the area was damaged. I

It’s essential to know that if the damage was caused by the user, Taurus might decline to fix it under warranty. So, be cautious and seek professional help if you come across this issue. I learned the hard way, and now I am passing on this knowledge to you!


The Taurus Model 66 is a firearm with a unique set of challenges and opportunities for customization and improvement. Throughout my testing, I’ve identified various problems, such as a shaking cylinder, misfiring, hammer, trigger, and front sight issues. 

Though these problems may raise concerns, my hands-on experience has shown that the solutions are often straightforward. 

Professional intervention may sometimes be needed, but most problems are fixable with proper care, attention, and understanding of the gun’s mechanics. 

The Taurus Model 66, despite its flaws, offers a good balance and functionality for its price. While it may lag behind its competitors in some aspects, it provides an opportunity for gun enthusiasts to learn, grow, and master the firearm.
