This video addresses common, 'not so stupid' questions about revolvers, explaining the function of the cylinder lockup nub, the purpose of the bent shield on the cylinder release, the mechanics of multiple cylinder lockup points, the reason for the enlarged rear frame on revolvers, and the distinctions between various barrel types. The instructor emphasizes that asking questions is a sign of growing interest in firearms, particularly revolvers, which he considers superior to semi-automatic pistols.

Quick Summary

The enlarged rear frame on revolvers is not just for aesthetics; it serves a vital safety function by protecting the primers of the cartridges. This enlarged area, whether a thicker frame body or a distinct shield, prevents accidental impact on the primers from external objects, thereby reducing the risk of unintended discharge.

Frequently Asked Questions

What is the purpose of the nub on the bottom of a revolver cylinder?

The small nub or extended piece on the bottom rear of a revolver cylinder is a crucial safety feature. Its primary function is to prevent the cylinder from accidentally sliding off its central post, ensuring the cylinder remains securely in place and aligned with the frame, thus preventing damage or separation.

Why is the shield around the cylinder release pin on some revolvers bent?

The bend in the shield around the cylinder release pin on certain revolvers acts as a ramp. This ramp is designed to guide the spring-loaded rear lockup pin smoothly as the cylinder closes, allowing it to retract gradually and then re-engage securely into its locking position without abrupt force.

What does it mean for a revolver cylinder to have multiple points of lockup?

Multiple points of lockup mean that the cylinder is secured by more than just the primary pin engaging the frame. This often includes an additional pin or feature on the front of the crane that engages a corresponding ramp or slot in the frame, providing a tighter, more stable lockup at both the rear and front of the cylinder.

What is the difference between a one-piece barrel and a two-piece barrel on a revolver?

A one-piece barrel is a single, solid component threaded directly into the firearm's frame. A two-piece or sleeved barrel consists of an inner barrel and an outer shroud or sleeve that are assembled together before being attached to the frame, often secured by a specialized nut.
