I'm looking for information on a Ruger 22/45 .22 cal long rifle hangun. This particular gun is unlike any photo found on Ruger's website. I requested info from Ruger and gave them model & serial number, but all I got back was that it was a KP4MKII made in November 1992. I would like to know why it was discontinued, and where I can buy extra magazines. I love this little .22, and take it along on every fishing trip into our backyard swamp. Mainly I am curious as to why I can't find another like it anywhere online. No history, no techinal info, no accessories. Even Ruger had no photos.
