Masterlock vs. Different Caliber Bullets
This video tests the ballistic resistance of a Masterlock against various firearm calibers. A .22 LR from a Ruger 10/22 caused minor damage, while a 9mm from a Glock 19 and a .45 ACP from a 1911 failed to penetrate significantly, leaving the lock functional. A 12 gauge slug, however, completely destroyed the lock.
