Had a .22LR/20 Gauge model, an old one with the nearly-full-length brazed barrels, many years ago. I put an early red dot sight on it (Weaver Quik-Point), and it was a huntin' machine. I decided one year to only use it for all my small/medium game hunting. On various hunts, I managed to harvest limits of rabbits, squirrel, partridge, grouse, ducks/geese (pre-steel-shot era) and dove (!), along with a few varmints and a fox. If I would have been drawn for a deer permit that year, I'd have used it for that as well (a 20 Gauge slug is nothing to sneeze at).
When shopping, check the stock for any damage near the wrist/pistol-grip area; if the stock loosens, shooting the shotgun barrel with a loose stock will often crack or chip the stock in this area.
My favorite story about this little gem centers around a multi-game cottontail rabbit and pheasant hunt. It was my turn to "bust brush", so I ducked-and-half-crawled into a dense thicket to push critters out ahead of the line of hunters, and during the brushy struggle, I managed to flip the hammer selector from shotgun to rimfire. When I squirmed out the other side of the thicket, just as I stood up, a pheasant flushed from right in front of me. I smoothly brought the gun up, cocking the hammer as I shouldered it, put the dot on the bird's tailfeathers (he was going straight away), and squeezed the trigger. Instead of the boom of the 20 gauge, I heard a "pop" of a .22 LR hollowpoint, and the bird dropped like a rock. I don't know who was most surprised; myself, my buddies, or the poor bird. The .22 had messed-up a bit of meat on one side of the bird, but it was worth it to make the shot of a lifetime (this, from a guy who often had trouble dropping pheasants with a scattergun).
I was just hoping we didn't get stopped for a game inspection on the way home; I didn't want to have to explain that bird's wound channel to a game warden...
Great little guns. I finally traded mine to a good friend when I left Alaska, as he had fallen in love with it when I let him use it to run his trap line a few times.
