Depends on what you are using a 59 for. Not the best for pass shooting, but for quick instinctive point and shoot there are few better. About the worst semi for that work would be a 12Ga 1100.
The 59 receiver was aluminum and the barrel wrapped fiberglass. Ugly as a wort, but few will match it for a Ruffed Grouse shotgun.
Agreed. I used one for awhile. Frank Woolner's grouse gun
