This guide, based on C&Rsenal's expert analysis, details how to visually distinguish between Single Action Only (SAO) and Double Action/Single Action (DA/SA) variants of the Nagant 1895 revolver. Key identification points include the presence or absence of a hammer nose pivot screw and the specific design of the hammer and rising block mechanisms. This information is crucial for collectors and enthusiasts identifying original configurations.

Quick Summary

Identify your Nagant 1895 variant by examining the hammer: Single Action Only (SAO) models lack a hammer nose pivot screw and feature a distinct 'beak', whereas Double Action/Single Action (DA/SA) models have this screw. Internally, SAO versions utilize a specific hook on the rising block that engages the hammer's beak, preventing double-action operation.

Frequently Asked Questions

How can I tell if my Nagant 1895 is Single Action Only (SAO) or Double Action/Single Action (DA/SA)?

Look at the hammer: SAO models lack a hammer nose pivot screw and have a 'beak', while DA/SA models possess this screw. Internally, SAO versions have a specific hook on the rising block that interacts with the hammer's beak.

Were Nagant 1895 revolvers originally Single Action Only?

Yes, the original Soldier's Model Nagant 1895 produced for the Russian military was Single Action Only (SAO). This design was chosen for cost and safety reasons, as double-action triggers were considered prone to accidental discharge under stress.

What are the key mechanical differences between the SAO and DA/SA Nagant 1895?

The primary difference lies in the hammer and the rising block mechanism. SAO models feature a hammer 'beak' and a corresponding hook on the rising block to prevent double-action function. DA/SA models have a standard hammer nose pivot screw and a plain rising block.

Why did the Russian military prefer SAO Nagants for soldiers?

The preference for SAO models stemmed from a desire to reduce costs by using fewer springs and a belief that SAO triggers were safer for soldiers in high-stress combat situations, minimizing the risk of accidental discharges.
