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.

This guide details how to check the timing on revolvers, a critical aspect of their mechanical function for safety and accuracy. The video demonstrates the correct procedure for both single-action and double-action modes, highlighting common failure points. Instruction comes from an expert with high technical knowledge of historical firearm mechanics.

This video provides an in-depth look at the unique cylinder rotation mechanism of the Jocelyn revolver, a five-shot, muzzle-loading percussion handgun issued to the Union Army during the Civil War. The presenter highlights how the gun's lockwork, particularly the hand and drum assembly, translates the linear motion of a rod connected to the hammer into the rotation of the cylinder, drawing parallels to the mechanism found in Swiss K31 straight-pull rifles. The video also touches on the revolver's reputation for being problematic in the field, with potential issues stemming from the cylinder-to-barrel boarding and the finicky nature of its side-hammer operation.

This expert-level analysis from Iraqveteran8888, featuring instructor Eric, debunks the myth that revolvers never jam. While generally reliable, revolvers can malfunction due to timing issues, worn parts like the 'hand,' improper ammunition, or user error like 'outrunning the gun.' The video highlights the significant disadvantages in reloading speed and capacity compared to modern semi-automatic pistols, especially under pressure. It emphasizes that understanding a firearm's mechanics and practicing its manual of arms is crucial for all weapon types, including revolvers.
