So first, a fortuitous story: last weekend, I stopped by at a gun show because there was nothing else happening last weekend. Normally, I don't find anything in the way of collectible Glocks, but it's always fun to go hunting anyway. At this show though, I happened on a pair of 21Cs and snagged them for $600! Couldn't believe they were that cheap so I figure I'll sell one to pay for the pair. But then things got better: I found a very nice "CM" prefix with matching bullet box and an '86 manual priced at $850. I didn't even bargain, just got the cash. A little later on that day, I was at a friend's table when someone came up and asked if they had any early Glocks. I showed him the new one and he made an offer I couldn't turn down: $500 cash and a new Sig M18 (which is currently selling on gunbroker for $999). Here's the kicker, I didn't remember the '86 manual so then I had a spare that I needed to take care of. Instead of re-inventing the wheel, I figured comic book collectors already had this figured out and picked up this starter kit. Has acid free sleeves and storage bin. I've now got all my early manuals sorted, tagged with what gun they belong with and protected for long term storage. Starter kit is on Amazon for $50 with bin, sleeves, and cardboard backers.
