Crimson Trace CTS-1550 Issues & Their Solutions

1. Durability and Construction Concerns

During my time with the Crimson Trace CTS-1550, I encountered a significant issue with its durability and construction. Although its compact and lightweight design is appealing, it didn’t quite hold up under rigorous use. 

Specifically, after several rounds of shooting, I noticed a problem with the red dot losing its zero. This was a major concern, as accuracy is critical for a red dot sight. Upon closer examination, it appeared that the issue was due to the emitter becoming loose within its housing. 


To address these durability concerns, I found a two-pronged approach to be effective. Firstly, ensuring that the sight is mounted securely on the firearm is vital. 

Regular checks for any loosening are essential to maintain accuracy. Secondly, if problems persist, particularly with the emitter or other components, contacting Crimson Trace directly is advisable. In my experience, they were responsive and offered a replacement once the product was available again. While it required some patience, their customer service was ultimately helpful in resolving the issue.

2. Battery Location and Auto-Brightness Issues

A notable issue with the Crimson Trace CTS-1550 Red Dot Sight is its battery placement and auto-brightness functionality. The battery is located underneath the sight, which poses a challenge during replacement. 

This design choice means that every time the battery needs changing, you might have to remove the sight from your firearm. This not only interrupts your workflow but could also necessitate re-zeroing the sight. 

Moreover, the auto-brightness feature, while a useful concept, doesn’t always perform optimally, especially in environments where lighting conditions change rapidly. 

I found that in certain scenarios, the auto-brightness didn’t adjust as quickly or accurately as needed, impacting the sight’s visibility and effectiveness.


To address the battery issue, I adopted a proactive approach. Regularly checking and replacing the battery before it completely drains helped avoid mid-use failures and unnecessary disruptions.

 As for the auto-brightness feature, I found that getting acquainted with the typical lighting conditions in which I used the sight was beneficial. By manually adjusting the brightness settings in anticipation of the environment, I could better ensure consistent sight performance. 

This preemptive adjustment meant I could rely on the sight to provide a clear and visible dot, regardless of the ambient light changes.

3. Impact Resistance

One of the more concerning issues I encountered was the sight’s fragility, especially when it came to impact resistance. 

During my use, a minor fall resulted in the sight glass breaking, which was quite disappointing considering it was equipped with its protective case.


The best approach here is to handle the sight with extra care. While it’s advertised as being robust, it’s better to avoid situations where it might get dropped or hit. 

If you do end up with a broken sight, reaching out to Crimson Trace for a warranty claim is your best bet, though be prepared for a potential wait in their response.
