SIG Reps Lie! SIG P250/P320 Comparison

Published on June 24, 2014
Duration: 4:40

This video provides a critical, in-depth comparison of the SIG Sauer P250 and P320 handguns, challenging SIG's claims about the P320's design origins. The speaker, demonstrating high expertise, highlights the modularity and interchangeable Fire Control Units (FCUs) of both models. Key differences lie in their firing mechanisms: the P250 is hammer-fired (DAO), while the P320 is striker-fired. The analysis covers frame modules, FCUs, slides, and sight configurations, offering valuable insights for firearm enthusiasts and those interested in SIG Sauer's modular pistol platforms.

Quick Summary

Expert analysis reveals the SIG Sauer P320 shares significant modular design elements with the P250, challenging claims of a 'ground up' design. Key differences lie in their firing systems: the P250 is hammer-fired (DAO), and the P320 is striker-fired. Both feature interchangeable Fire Control Units (FCUs) and modular grip modules.

Frequently Asked Questions

What is the main difference between the SIG Sauer P250 and P320?

The primary functional difference is their firing system: the P250 is hammer-fired (Double Action Only), while the P320 is striker-fired. Both share a modular design with interchangeable Fire Control Units (FCUs).

Are the SIG P250 and P320 frames interchangeable?

Yes, the polymer grip modules of the SIG P250 and P320 are virtually identical and designed for modularity. Their serialized Fire Control Units (FCUs) are also interchangeable between compatible frames.

Did SIG Sauer design the P320 from scratch?

According to expert analysis, the SIG P320 appears to be heavily based on the P250 platform, sharing significant modular components and design lineage, rather than being a completely new design from the ground up.

What are the key internal components of the SIG P250 and P320?

Both pistols utilize a modular polymer grip module and a serialized Fire Control Unit (FCU). The P250's FCU is for a hammer-fired system, while the P320's FCU is for a striker-fired system. The slides also differ in their internal mechanisms.
