Indeed, theyre almost always "residential security containers" at best. Which means the manufacturer can't even be bothered to assert that it would take 5 minute to break in to with hand tools.

I would have thought things like ISM would be top quality consumer grade.

They are, but they are far more expensive than mainstream consumer gun "safes" and very heavy.

A buddy of mine's dad dealt in wholesale jewelry and my friend inherited one of his dad's safes (I don't recall the brand offhand). It's over 5,000 pounds, has a tempered glass relocking plate in the door to defeat drills, etc. It is far beyond what almost any gun owner would go for. If something were to somehow fire the relockers, it would be an expensive proposition to get into the safe afterwards.

I would guess that would be commercial grade if he was involved in that business.

ISM makes TL rated safes. Actual security devices. This is the entry level of what you might need as a business owners.

They’re more expensive than what 99% of homeowners put inside of their safes.
