Sig P320 Five X Legion shots ---case extraction issues?

This 2 minute video is of shooting Sig P320 Five X Legion 9mm. A detail range review will follow. What was surprising to me in the first 250 round test, was the very inconsistent ejection pattern. Stay tuned for the next installment. UPDATE: Swapped springs and the gun is now 100%. No issues. Detailed range review will be posted October 11, 2019
