My experience shooting ported guns has not yielded any of the negatives people claim it will (or could) with one exception; the front sight gets dirty very quickly. My preferred setup is an Ameriglo Proglo front and plain black rear but I am not sure how well it would work with my ported Shield. So I decided to go another way, Truglo TFO PT sights. The only place I know of that sells these are Brownells and they run around $65. With the practical tactical sights I get a glowing front sight (fiber optic and tritium) and a plain black serrated rear. The best part is that the front sight is so long that it sits well behind the porting. I only had time to pop off one mag to test it out, but so far so good! I am hoping to get some range time next weekend to put it through a little more extensive testing.
