I had a J-22 until last year, it was given to me about 15 years ago. I finally totally gave up on the gun. I couldn't bear the thought of sticking anyone with that horrible thing, so I fired up the Dremel Tool and cut the receiver and slide in two, and discarded them. I kept the magazine and the grips, in case I ever ran across someone that wanted them, but IMO the J-22 is pure junk!
