right now i just use a laptop bag. it's a little oversize for today's laptops, i got it back when i had a laptop, which was 8 or 9 years ago. i stick to desktops now, with how easy it is to find a PC at any hotel, library, etc. i prefer the power and ease of maintenance of desktops. anyway, it's nice, the main compartment comfortably holds a large sig hard case, and could almost fit 2 usp compact hard cases. the rear compartment is basically one of those stretch-out folder type compartments, where i can stack a box of ammo in a partition and also keep targets, dry stuff, etc. the front pocket is rounder, so that's where i keep cleaning supplies. i can stuff earplugs/muffs and glasses pretty much anywhere, and i'm good to go, for a couple pistols at least.
