If you are looking for a single or double pistol safe you might try searching for pistol vault or similar. If you need 1'x1'x1' or so, you might do better searching for a small cash or deposit style safe. Typically pistol safes are small bolt-down 16-10 gauge metal boxes and gun safes are 350+ lb units starting at 50" tall or so.
IMHO, having a small safe and not bolting it down is the same as putting a large neon sign on everything in the safe that says "STEAL ME". You'd do better to find or make good hiding places including fake registers, cleaning supply boxes, etc rather than spending cash on a small safe you do not intend to bolt down. $5 in hardware and 20 minutes of work is worth it to secure a $200 safe and $1k in guns, ammo, and valuables. Even if you are renting, you have at most $10 and 20 minutes of patching and touch-up when you move out. There are dozens of stories on this forum on how even large safes were damaged, opened, or removed because they were not bolted down.
