Why modern revolvers lock up tighter

Duration: 1:55

The video debunks the notion that modern revolvers are less precisely fitted than older models. It explains that while older mass-produced revolvers often required significant hand-fitting, modern CNC machining allows for exceptionally tight tolerances right off the production line. The speaker highlights that components like tangs on revolvers, such as Rugers, are finished only as much as necessary, especially when covered by grips, and that modern revolvers exhibit minimal cylinder or barrel wiggle compared to some older examples.

Quick Summary

Modern revolvers lock up significantly tighter than many older models due to advanced CNC machining, which ensures precise tolerances from the factory. While older revolvers often required hand-fitting, leading to variable lock-up, new firearms exhibit minimal cylinder and barrel wiggle, offering superior mechanical tightness.

Frequently Asked Questions

Why do modern revolvers seem to lock up tighter than older ones?

Modern revolvers benefit from advanced CNC machining, which allows for extremely precise manufacturing tolerances right off the production line. This contrasts with older mass-produced revolvers that often required significant hand-fitting, which could lead to less consistent or tighter initial lock-up.

Does the finishing of a revolver's tang matter for its performance?

The finishing of a revolver's tang is primarily aesthetic and functional only if exposed. For revolvers like some Rugers, where the tang is covered by the grip, extensive polishing or finishing is unnecessary as it doesn't impact the firearm's operation or lock-up.

Are older revolvers inherently looser than new ones?

While some older revolvers may exhibit more perceived looseness due to hand-fitting processes, modern revolvers manufactured with CNC technology generally achieve much tighter lock-up and part fit. This results in less wiggle in the cylinder and barrel, even on new firearms.

What is the difference in part fitting between vintage and modern revolvers?

Vintage revolvers often relied on skilled gunsmiths for hand-fitting parts to achieve desired tolerances. Modern revolvers utilize CNC machining, which automates this process with high precision, leading to consistently tighter fits and less play in components like the cylinder and barrel.
