Just so everyone knows, this is my first post. I've already read everything and checked everywhere, so don't worry.
Yesterday I picked up a few Triads for an integration idea I had. Today I went to take them appart. I drilled to hole, took the trigger out of both, almost had the entire thing apart, just one peice left, the orange barrel tips.
I'll get pictures ASAP, but basically on both of the Triads, there is a metal pin in place of the screw on the front of the pistol. It's the screw port in the center of the three barrels.
Is this a problem other people have overcome? Did I miss something? So far I don't know how to overcome this issue, I've warped the plastic on one of them with vice grips trying to pry it off. Toughts?
Again, pictures are on the way.
