"...Simple explanation for doing it..." Mean you don't need to install an aftermarket compensator. Doing that alters how the slide works and you have to fiddle with springs.
"...it may slow the bullet a little..." Nope. In the microseconds between the time the bullet passes through the compensator and the gasses follow, the bullet is already out of the barrel. It has all the speed it's ever going to get. The gases do nothing but push the muzzle down.
"...a .45 ACP with a 3.5" barrel..." That'd be more of a consideration than the porting. Muzzle blast isn't going to be pleasant no matter what you do.
