Frequently Asked Questions

What are the potential causes of an uncommanded discharge in a modified CZ Shadow 2?

Potential causes include a combination of factors such as an extended firing pin, a weakened or binding firing pin spring, high primers, and forceful manipulation during holstering or drawing, which can collectively lead to unintentional ignition.

How does modifying the firing pin return spring affect a CZ pistol?

Lightening the firing pin return spring reduces the force needed from the hammer to ignite the primer, potentially leading to a lighter trigger pull. However, it can also make the firing pin move more freely and may compromise safety features if not done correctly.

What is the difference between the CZ Shadow 2 and the Sig P320 regarding discharge incidents?

Incidents with the CZ Shadow 2 are often linked to aftermarket modifications affecting its mechanics, whereas Sig P320 issues were more frequently associated with potential factory design or manufacturing concerns.

Why is caution advised with heavily modified firearms like the CZ Shadow 2?

Extreme modifications, especially those altering trigger pull weight or firing pin behavior, can significantly reduce a firearm's safety margins, including drop safety and reliability, increasing the risk of accidental discharges.
