The benefit of having both systems would enable me to have everything I want on the gun. I definitely want a forward verticle grip so I have to have a lower rail system, I could incorporate the light at that point which is why I was interested in the surefire setup to include their light.
If I want to have 6 or so shells on the gun, then I will need to have something incorportated into the upper picatinny rail system. I could just keep the mesa system I have now or go with something like the side armor, either will allow me to mount something from trijicon!
Either way, the KZ system I already posted a link to would be perfect but I cant find anyone that has that setup. I also cant decide if the 14 shell holder is going to far for on the gun ammo for various reasons, but I would be able to mount whatever I wanted with that system. I'm not worried about the weight as long as the gun functions properly but obviously the lighter the better!
I have a headache!
