Polymer VS. OE Glock Magazines
This video compares the durability of OEM Glock magazines against aftermarket polymer magazines (ETS, Magpul) through a series of torture tests. The instructor, with extensive experience in firearm abuse testing, demonstrates that stock Glock magazines, despite cosmetic damage, maintain functionality through extreme conditions like being buried in dirt and ground into the earth. Aftermarket polymer magazines, in contrast, showed significant functional issues under similar stress.
