I would suggest getting the port professionally done, or just leave it be. Otherwise you will end up with that hacked look, (prime pictorial examples in this thread), and for what? It really won't make a significant difference in the speed of your reloads. Keep you gun pretty, invest in a par timer, and practice practice practice.
I think that is more of a function-before-fashion look vs. hacked look. Don't know about others, but I beveled the mag well because that edge can be a tad sharp when weak hand reloading.
If one has the $ to burn on a fastfire, it'd add the button as well.
