Kev, back in the mid 80s, Iver Johnson sold a little .22lr called the TP-22. It was a Walther PPK knockoff, scaled down. Same take down and everything. The slide and frame were cheap zinc based, but the fixed barrel was steel. Oddly enough, the gun I owned functioned reliably with every mixed round I fired through it and it was a pretty accurate little beast as well. I'm trying to recall, but the magazine I believe held 6 rounds. It was a true "pocket" gun! I killed many a West Texas grass hopper (about the size of a humming bird!) and not just a few rattle snakes on the black top roads at night.
It was a comforting little gun to have tucked away where no one knew it was there.
