I would check out Dick's then. They are reasonably priced, and are decent safes.I guess as I look online at models I am thinking 12-24 guns so more of a medium size since i am seeing 31 and 45 gun cases. I would like to have room for some rilfes and have a few shelves in it as well. I have see some where it it broke down with 8-12 rifles in half and shelves in the other half.
I have their 36 gun safe. I would recommend it as well.I picked up a Stack-On Total Defesne Select. It is a 45 gun unit. That would be 45 pump shotguns, or single shot. If it has a bolt or charging handle that takes up about a 1/2 spot on its own. I would almost figure a capacity as 2/3 of what they say. If you have a Rural King nearby check out the Stack-On Total Defesne line.
