I ended up going back to G. M . to buy a Liberty safe .
I looked at the Stack OnSafes and the Cannon safes and like the Liberty line much better ,
Mine has the better lock and fire rating .
Iwent with the Liberty Timber Ridge Series TR25 .
Suppose to hold 25 rifles .
Well I dont have quite near that many so I ,ll have extra room .
Just nead to keep the wifes things out .. LOL....
Upgrading to this safe I went to a better 45 min .verses 30 min. and higher ( hotter) fire rating than the C-20 and also this safe is made in the USA .
And has 11 active bolts around the door instead of 4 .
This one is the green speckled one with the gold 3 bar handle .
Gander gave me a heck of a deal . $100. more then the c20 model .
Thanks for the tips ....
