Look for safes with 1/8" steel walls, minimum 10 gauge. The thin gauge wall is a joke. 3/8" plate on the door. The big box stores safes have 10-12-14 ga steel walls , a circular saw with a proper blade goes through that like a hot butter knife ...
Also looking for another safe .
That Cannon safe at TS has 14 gauge steel walls composite construction. Looks real good , but keep looking !!!!
