I own a 1300 but have never had the receiver drilled & tapped.
The main issue is it is aluminum. Good grades of aluminum can be tapped and hold, but it's not normally recommend. The best with aluminum is to use a heli-coil steel insert. Then you can hold about the same as with steel.
Having said that, it would be up to a gun smith to give you the final answer.
PS. I will get my 1300 out and take a look just to see how it could be tapped.
