Yeah...that's gorgeous! I can understand the desire for the porting (BTW, it typically doesn't reduce velocity as much as people think). Porting is great...but at typical self-defense ranges you might well find yourself shooting "from retention" as the IDPA guys put it...i.e. with your arm in close to the body immediately after a draw...and in that situation porting might not be such a good thing. Better to shoot ammo you can handle without porting, I think...
I'd thought about getting a small pistol in .40 and having it ported...until the first time I shot my LCP9s "from retention" and realized how up-close-and-personal the blast is even without porting and from a little 9mm...it really surprised me. I've been shooting for years, including a lot of steel plate stuff and what have you, using ported guns...but that was my first experience shooting basically from just in front of my own belly...
