There is no such thing as +p 40 as far as I know, all 40 should be standard pressure, although some may push the edge.
Using a gofast 10mm is simply over-kill (literally) and it will not go unnoticed by those who want to see you fry for carrying.
I'll say it again.. use what your local PD uses. You are faultless with that.
