Yep they are indeed alumagrips w/ the gungrips dragon logo, and birchm's right, its a magna SD springfield slide.
Nice guns airwolfie. The TLE/RLII frames seem a bit odd with GSR slides to me but still its a cool set you got there.
It's a KSC "Air Forse" (gotta love their spelling) barrel. It's a one piece threaded barrel, which I'm not so hot on because its plastic, but it comes with a badass aluminum thread protector. Let me see if I can get some better shots up.
/Edit
Here are some better views.
Nice guns so far guys. Here are my berettas, a ksc m93r and m9. I'm still looking for one of my dream guns, the WA Cougar
As an aside, how the hell do you get the inner barrel out of a ksc m9 outer barrel? It seems stuck in there pretty good.
