In Aldi they've got a variety of laptop bags. One of them has 4 padded compartments and could be used as a carry case for 4 pistols.
I didn't get one as it was a light brown colour which didn't look very nice, but I'm keeping my eye out for other colours.
i bought a set of 3 hard cases from bnq last week for £9 excellent pistol cases
