Is it fair to assume that a used pistol, maybe with just 2 mags, would cost about 1/2 that?
No.
The "value" of an object is what it will trade for between a willing buyer and a willing seller, neither of which is required to engage in the transaction and both of whom are aware of all relevant facts.
If the market values a used gun at half what a new one sells for, then it would be worth half as much. If the market values it equal to a new one, then expect to pay what a new one would cost.
...I'm wondering how you guys find deals.
Become familiar with the marketplace (both on-line and local) for the used gun you are interested in buying. See what sellers are asking for the guns and realize that in the ensuing negotiation process the actual price at which the gun changes hand almost never goes up.
Learn how the gun you are interested in ages, what problems it develops and what accessories it should come with. From there you will be able to inspect the gun you are interested in and point out the things that make it less valuable to you and negotiate for a lower price.
Can you guys help me with what I am missing?
Psychology. If I bought an AR during the panic for $600 and today it is on the rack at Academy for $400, I may have a hard time psychologically and emotionally parting with it for less than $400. It is not a question of "value", but affection and nostalgia and you would be surprised how much value people can place on those intangibles that may be worthless to you.
Also, be aware that some sellers charge a lot for used guns because they plan to meet the buyer and transact the sale in person so that no background check or ATF paperwork is involves. The buyer may not be legally qualified to own a gun and so is willing to pay more an "off the books" gun than for a new one because he cannot buy a new one.

Finally, I should mention that there are people (like me) in the market that in the real estate would would be called "bottom feeders" who wait around sellers that are obviously distressed waiting for the chance to buy all or a segment of their inventory for a very advantageous price. The presence of "bottom feeders" in any market serves to put a floor under prices that might otherwise go lower. After all, if a seller knows all he/she has to do is pick up the phone and they can get 45-47 cents on the dollar for, say, all the revolvers in their inventory, they are unlikely to sell a lone gun to you for even 50 cents on the dollar since one big check is a lot easier than chasing after a bunch of little ones.
