usable space
These look like good products.
Betty's link lists both the outer dimensions and the inside dimensions of the Gun Vault.
Euclidean, the Secure Vault page gives one set of dimensions (12.75” x 9.2” x 7.5”) for your model 33013. Could you check to see if these are the outer or inner dimensions?
Only at rare intervals is anyone in my house other than my wife or me, so I have not given much thought to these safes until recently. But I have too much imagination and have thought of an intruder finding my stash of pistols and ammunition, loading a pistol, and using it to assist further criminal activity.
So I am thinking of possibly 2 safes: one for pistols I am not carrying and one for ammunition, since I don't think I could squeeze it all into one of these.
