I was actually given this pistol (a 30 round 22 magnum) in its original box with two mags. it is the longer version with the muzzle break.. as previously stated, it was given to my when my father was unable to get the mag release to work properly, as it turns out, it only needed a new spring which my gunsmith did quickly and easily... so I am just curious to learn anything I can about this "interesting" gun..
