Does anyone have any sources or designs for a range tote large enough for 6 handguns and range essentials? I have used the same 25 year old range bag but want more separation, organization and handgun protection. I'm thinking that I will have to custom build with wood. Padded mail slots for the handguns in a row with ammo stored on a shelf below (access by side opening door). Top opening area to store smaller accessories and targets. Any design experience and pictures you would like to share that has worked out well?
