I know of several Rem. 597M's around here, i own one myself. I've not heard of even one of them being recalled and all of them i know of, work perfectly!
As for the Henry pump, RUN AWAY from it as fast as you can! I also had one of those POS's! Buy a Henry lever in 22 mag., they work smoooooothly and are a great 22 mag...
