Many shotguns have a too long, length of pull. It is a common issue.

I am getting ready to cut my Browning A5, and get a pad that is grind to fit. I am slow to cut my 1960 stock
though, it is almost as old as I am.....oh well....

I am often using this gun during late pheasant season, hunting coat, etc. I have short arms and need
to make things fit better.
