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