Why adding a 7th round could hurt a Python's trigger

This video discusses the potential mechanical challenges of modifying a Colt Python revolver to accept a seven-round cylinder, drawing parallels to the S&W 686 and Ruger GP100. The speaker hypothesizes that the Python's specific cylinder locking mechanism, which engages the cylinder stop and hand very late in the trigger pull, could be stressed by the increased cylinder diameter and rotation required for an additional round. This might lead to a less smooth trigger pull or increased wear on internal components, potentially explaining why Colt has historically opted for a six-round cylinder in the Python.

Quick Summary

Adding a 7th round to a Colt Python could negatively impact its trigger by stressing the late-engaging cylinder stop and hand mechanism. This might result in a less smooth, 'jerkier' trigger pull, a trade-off many Python owners would likely avoid.

Frequently Asked Questions

Why might a 7-round cylinder be problematic for a Colt Python?

A 7-round cylinder could stress the Python's specific cylinder stop and hand mechanism, which engages very late in the trigger pull. This might lead to a jerkier trigger action and increased wear on internal parts, potentially compromising the smooth trigger pull that Python owners value.

How does the Colt Python's cylinder locking mechanism differ from other revolvers?

The Colt Python's design engages its cylinder stop and hand extremely late in the trigger pull, almost at the last moment before firing. This precise timing contributes to its smooth trigger but could be a point of failure if the cylinder diameter increases for an extra round.

Could a 7-round cylinder affect the Python's trigger pull smoothness?

Yes, it's hypothesized that a 7-round cylinder modification could make the Python's trigger pull 'jerkier' and less smooth. This is due to the increased mechanical complexity and potential stress on the timing mechanisms required to rotate and lock a larger cylinder.

Are older Colt Pythons different in their trigger mechanism compared to newer ones?

Yes, older Colt Pythons had a cylinder stop that engaged later in the rotation cycle. Newer models have the cylinder stop engaging earlier, which is a key difference that affects the trigger feel and timing.
