That said, despite its reputation, the Colt Python isn’t without flaws. The biggest issues I’ve experienced include timing problems, cylinder misalignment, light primer strikes, and action wear leading to lock-up failures. While these don’t ruin the revolver’s overall reliability, they can impact performance and require attention. Alright, let's take a detailed look at the most troublesome Colt Python issues and how they can be easily solved.
Colt Python Problems: Colt Python cylinder misalignment issue and how to fix it
One of the most frustrating Colt Python problems is cylinder misalignment. I’ve experienced this issue firsthand, and it can seriously affect both accuracy and safety. When the cylinder doesn’t properly align with the barrel, it can cause spitting lead, where hot gases and bullet fragments escape from the cylinder gap, increasing the risk of injury.
The Colt Python’s precision machining is one of its defining features, but over time, wear on the hand and cylinder stop can lead to misalignment. This problem becomes more apparent when firing high-powered .357 Magnum loads, as the increased recoil accelerates internal wear. Some shooters report experiencing noticeable timing issues, where the cylinder doesn’t lock up properly before the hammer falls. This can result in inconsistent bullet exit paths, reducing accuracy and potentially damaging the forcing cone over time. If left unaddressed, Colt Python cylinder misalignment can turn into a serious functional defect.
How to solve Colt Python cylinder misalignment problem
Addressing the Colt Python cylinder misalignment problem requires a systematic approach to ensure both safety and optimal performance. Here's how you can tackle this issue.
- Thorough Cleaning and Lubrication: Residue buildup can impede the cylinder's proper alignment. Begin by performing a meticulous cleaning of the revolver, focusing on the cylinder, crane, and locking mechanisms. After cleaning, apply appropriate lubrication to ensure smooth operation.
- Inspect and Tighten External Screws: Loose screws can contribute to misalignment. Remove the grips to access the frame screws and ensure they are securely tightened. This simple step has resolved binding issues for some users.
- Check for Cylinder End-Shake: Excessive forward and backward movement, known as end-shake, can cause misalignment. If you detect noticeable play in the cylinder, it's advisable to consult a qualified gunsmith for assessment and potential correction.
- Examine the Cylinder Stop and Hand Mechanism: Wear or damage to the cylinder stop (bolt) or the hand can lead to timing issues. A professional gunsmith can evaluate these components and perform necessary adjustments to restore proper timing and alignment.
- Consult Colt's Customer Service: If the problem persists after these steps, contacting Colt's customer service is recommended. They can provide guidance or arrange for the revolver to be serviced by their technicians.
By following these steps, you can effectively address the cylinder misalignment issue and maintain the reliability of your Colt Python.
Colt Python Problems: Colt Python light primer strikes issue and how to fix it

Another frustrating Colt Python problem is light primer strikes, an issue I’ve encountered firsthand. When pulling the trigger, the hammer falls, but the round fails to fire due to insufficient force applied to the primer. This can be a serious reliability concern, especially for those using the Colt Python for home defense or range shooting.
The Colt Python’s finely tuned double-action/single-action trigger is known for its smooth pull, but some shooters report inconsistent ignition, particularly in double-action mode. This issue often stems from insufficient mainspring tension, worn or altered firing pin components, or the use of hard-primer ammunition like certain .357 Magnum or .38 Special rounds. Over time, regular use can also lead to slight hammer spring wear, reducing the force transferred to the firing pin. If left unresolved, Colt Python light primer strikes can significantly affect reliability, requiring repeated trigger pulls to fire a round.
How to solve Colt Python light primer strikes problem
To resolve the Colt Python light primer strikes issue, consider the following steps:.
- Use High-Quality, SAAMI-Certified Ammunition: Colt recommends using high-quality, SAAMI-certified, brass-cased ammunition in the Python, as imported ammunition with harder primers may contribute to light primer strikes.
- Increase Mainspring Tension: Colt has addressed light primer strikes by increasing the tension of the mainspring in newer Python models. This adjustment enhances the hammer's force, reducing the likelihood of light strikes.
- Consult a Professional Gunsmith: If the problem persists, consult a qualified gunsmith. They can assess the firing pin protrusion and mainspring tension, performing necessary adjustments to ensure reliable primer ignition.
By following these steps, you can effectively resolve light primer strikes and maintain the reliability of your Colt Python. For a detailed discussion on addressing light primer strikes in Colt Pythons, you can refer to this Reddit thread.
Colt Python Problems: Colt Python action wear issue and how to fix it
One of the more concerning Colt Python problems is action wear leading to lock-up failures, an issue I’ve encountered after extended use. Over time, the intricate timing mechanism of the Colt Python’s action can wear down, leading to incomplete cylinder lock-up before the hammer falls. This not only affects accuracy but can also pose a safety risk, as a misaligned chamber increases the chance of forcing cone damage or lead spitting.
The Colt Python relies on a finely tuned hand, bolt, and ratchet system to ensure the cylinder locks in place before firing. However, excessive dry-firing, frequent high-powered .357 Magnum loads, or lack of proper maintenance can accelerate wear on these components. Shooters have reported instances where the cylinder fails to fully rotate into position, requiring manual adjustment or resulting in a sluggish, inconsistent trigger pull. If left unchecked, Colt Python lock-up failures can compromise both performance and longevity.
How to solve Colt Python action wear problem
To address Colt Python action wear leading to lock-up failures, consider the following steps.
- Regular Maintenance and Inspection: Perform routine cleaning and lubrication to minimize wear on internal components. Regularly inspect the cylinder locking bolt and related parts for signs of wear or damage.
- Consult a Qualified Gunsmith: If you notice timing issues or lock-up failures, it's advisable to consult a gunsmith experienced with Colt revolvers. They can assess the action's timing and make precise adjustments to ensure proper function.
- Utilize Colt's Repair Services: Colt continues to offer repair services for the Python. Sending your revolver to the manufacturer ensures that any timing or lock-up issues are addressed by professionals familiar with the firearm's design.
By following these steps, you can effectively address action wear and maintain the reliability of your Colt Python. For a detailed discussion on checking and addressing lock-up issues in Colt Pythons, you can refer to this Colt Forum thread.
