The Sig Finally Fails
This video details a failure point identified in Sig Sauer P320/M18 OEM magazines during extensive testing. The instructor, who professionally trains individuals and observes high round counts, experienced a cracked magazine at approximately 6,000 rounds. This is presented as a significant issue because the magazines were previously considered the only strong point of the Sig platform, especially when compared to the perceived durability of Glock magazines tested under similar conditions.
