Ive got an intratec tec22 that I got years ago in a trade. In 16 years Ive put about 200 rounds through it, mostly because it was absolutely unusable until I bought the ruger hicap mag with the metal feed lips. As soon as I bought that, the weapon, surprisingly, operated flawlessly. I'm cleaning house and have no use for it. looking on gun broker Im seeing prices of $450-600. Am I seeing it right? Is the price really up there?
