Glock 26 Jams with G17 Mag: Nutnfancy "Trench Warfare" Drill

More surprising results coming out of the Nutnfancy RunNGun Drills. Here I run a very proven and reliable Glock 26 in the Trench Warfare testing drill on steel plates (www.shopactiontarget.com). It is extremely accurate and fast to shoot...but it holds a surprise for us as I slam in Glock 17 mags without a gapper./////////////Note: Mags used were all in excellent condition. The Glock 17 mags were new.
