PopMech posted an interesting story testing multiple padlocks against multiple stressors including a “Salt Fog” test for rust resistance and, it seems, a gun test.
Not to spoil things, but the Master lock was the only one that survived a gunshot to the gut. Everyone else shattered and ran away crying.
