Do what your Daddy says. Go shoot something. And repeat frequently.
The 11, or Remington Auto in its earliest version was a very good shotgun. In your shoes, I'd get it to a decent smith to check whether or not it needed anything. Sometimes the fiber buffer in the receiver needs replacement to avoid battering some parts. Sometimes the springs are just plain tired.
I inherited a newer 11, circa 1930 something. A smith replaced all the springs and called it a 10K round rebuild. Works fine, a cousin has it now and loves it.
