Videos tagged with Internal Cylinder Retention

This video explains the 'bump' or 'lug' found on older revolvers, identifying it as a frame or cylinder lug. Its primary function is to prevent the cylinder from falling off the ejector rod when opened. The video details how these lugs can be integrated into the frame, pinned, or part of the side plate, and contrasts this with modern revolvers that utilize internal mechanisms with ball bearings for cylinder retention, making the external lug obsolete. The presenter notes that while older methods required hand-fitting, newer designs are easier to manufacture.
