Shadow 2 drop test

Published on May 29, 2024
Duration: 4:29

This video discusses the drop safety of the CZ Shadow 2, particularly in the context of modifications common in USPSA competition. Ben Stoeger explains how lightening the firing pin spring or using an extended firing pin can compromise the firearm's drop safety. He demonstrates that a factory-stock Shadow 2, while not inherently drop-safe on a single impact, requires multiple muzzle impacts to detonate a primer.

Quick Summary

A factory-stock CZ Shadow 2 requires multiple direct muzzle impacts, at least two, to detonate a primer. Common modifications like lightening the firing pin spring or installing an extended firing pin can significantly reduce its drop safety, making it more prone to accidental discharge upon impact.

Frequently Asked Questions

Can a CZ Shadow 2 be modified to be unsafe when dropped?

Yes, common modifications like lightening the firing pin spring or installing an extended firing pin can compromise the drop safety of a CZ Shadow 2, making it more prone to accidental discharge upon impact.

How many times does a factory CZ Shadow 2 need to be dropped to detonate a primer?

According to Ben Stoeger's testing, a factory-stock CZ Shadow 2 requires multiple direct muzzle impacts, at least two, to detonate a primer. A single drop was not sufficient in his tests.

Why do competitive shooters modify the firing pin spring on CZ Shadow 2 pistols?

Competitive shooters often lighten the firing pin spring on CZ Shadow 2s to achieve a lighter double-action trigger pull and a slightly lighter single-action pull, which can improve shooting performance.

Is the CZ Shadow 2 considered a drop-safe firearm?

A factory-stock CZ Shadow 2 is not inherently drop-safe on a single impact. Modifications, particularly to the firing pin and its spring, can significantly reduce its drop safety.
