SIG P320 XTEN Vs. SIG P320 M17 (Part 1) - 10mm Vs. 9mm with Navy SEAL Mark "Coch" Cochiolo

Published on August 15, 2022
Duration: 8:53

This video compares the SIG P320 M17 in 9mm against the SIG P320 XTen in 10mm through a series of timed drills. Navy SEAL Mark "Coch" Cochiolo assesses accuracy, speed, and recoil impulse differences. The comparison highlights that while 10mm offers more power, it results in slightly slower times and wider group spreads due to increased recoil, though the platforms themselves feel similar.

Quick Summary

The SIG P320 XTen (10mm) offers more power than the SIG P320 M17 (9mm) but results in slightly slower times and wider shot groups due to increased recoil impulse. While the platforms feel similar, the 10mm's 'snappier' recoil requires more management, though this can be overcome with consistent training.

Frequently Asked Questions

What are the main differences between the SIG P320 XTen (10mm) and the SIG P320 M17 (9mm) in terms of performance?

The SIG P320 XTen in 10mm offers greater power but exhibits a 'snappier' recoil impulse, leading to slightly slower times and wider shot groups in drills compared to the 9mm SIG P320 M17. The M17 generally proved faster and more accurate in rapid-fire scenarios.

How does the recoil of the 10mm affect shooting speed and accuracy compared to 9mm?

The increased recoil impulse of the 10mm makes it slightly more challenging to manage during rapid fire, resulting in wider shot spreads and marginally slower times. The 9mm's lighter recoil allows for quicker follow-up shots and tighter groupings in timed drills.

Are the SIG P320 XTen and P320 M17 physically similar to shoot?

Yes, the SIG P320 XTen and P320 M17 feel very similar in hand, with the XTen being only slightly heavier. The draw stroke, presentation, and overall handling are comparable, with the primary difference being the recoil impulse of the ammunition.

Can the recoil of the 10mm be overcome with training?

According to the instructor, with sufficient training and practice, the recoil impulse of the 10mm can be effectively mitigated. He believes that consistent repetition can help shooters overcome the slight speed and accuracy differences observed.
