Okay, I've been thinking about "investing" in a range bag for some time. I need something a little bigger than my gov't issue mechanic's bag. I figure it needs to be big enough to tote two pistols, 300 rounds of ammo, a cleaning kit, spare mags for both pistols, muffs and glasses. Something I don't have yet, but figure I REALLY need a hardwood dowel and hammer for squibs. What other items are must-haves for a range bag?
