Personally, I wouldn't carry my dirty socks in a Plano. It's Pelican or nothing.
Plano is fine for tackle boxes. Thats about it.
Always trace the outline of the firearm on the backside, backwards from what it will be and cut it with an electric carving knife or a serrated hand knife holding the knife vertical and cut on the INSIDE of the outline.
