For high quality I was in the market for a real leather gun rug, with suede on the inside. I also wanted a Colt logo embroided on the case. But alas I never found what I was looking for, this one though intrigued me:
Great medium size bag. Technically it's a bailout bag, but has plenty of pockets for magazines (designed for AR/M4 mags, but fits auto mags and speedloaders just fine), etc., even has a lined pocket in the front that fits up to two medium-sized autos. Internal pocket is quite spacious; I can stack 6-8 50 rd. ammo boxes on one side of it and still have the other half with plenty of room, and it comes with a removable divider. Plenty of other zipper pockets of various sizes as well.
Comes in coyote, olive green, and black. And best of all, right now it's only $20; hence why I jumped on it and got mine
5.11 Tactical & Blackhawk(started by a retired US Navy SEAL) have good kits & cases.
The Pelican line is good too. They are airline/TSA approved & come in many colors-sizes(including clear).
FWIW; I always use a Bore-Store treated bag as a 2nd layer of protection when I go to the field or range. They aid in preventing nicks, scuffs, etc.
