Those same Glock 22s were $279 just a few months ago.
I bought a couple of police trade-in 40's for $299, but that was in 2011 or so. They haven't been below $399 there for years now.
Those 21s are probably one of the best deals out there (these days) for these first-time folks looking for literally anything to protect themselves with.
I don't know if Glock is still open for refurbishing, but even without that these would still make good car or home defense guns, and 45 ACP seem a little more available than 9mm right now.
