I've owned this M34-1 1970 .22 for about 5yrs . It looked rough when I got it, rusty, would not eject empties, no grips....Owner threw in new package S&W magnas....I cleaned it up good as I could, finish reamed cyl..copper chore boy and oil on outside and today got my grip adapter from BK grips...that's what it needed!...Now these big old mitts get a better grip...carry it squirrel hunting...close as I'll get to the ideal kit gun
