Brand New Masterlocks Vs. Increasing Calibers #bulletproof #gun #locks
This video tests the durability of Masterlock M175 combination padlocks against various firearm calibers. While .22LR, 9mm, and .45 ACP rounds caused damage, the locks remained functional. An AR-15 inflicted significant damage, but the lock stayed secured. Only a 12-gauge shotgun slug was able to destroy the lock and release the shackle.
