I personally would not be comfortable with FoS less than 3.0 if I am holding the thing in my hand.
The first thing I thought of reading the post was - pressure vessel design - which has direct similarities to gun barrels.
Not knowing what the mil spec was, or some rule of thumb design factors from a very trusted source, I would consider reviewing some of the industry standards for FoS which you can find here:

Hope that helps!
