So i just got my gorgeous G&P today and like any other fanatic, i want to get upclose and personal. My first impression/dissapointment is that the gun is quite light. Lighter then i would have expected it to be, i'm not sure if this is normal or not. But from the description it says its vitually all metal. I'll assume its all aluminum.
But anyways, i want to crack that baby open and peek about its guts, but when i went to attempt to remove the body pins, i realized that these things are super jammed in there. I mean super stuck, i placed it onto a carpeted floor and with a Philips screwdriver, pushed on it harder and harder until it finally shot outta there. But the front one is even tougher.
I ain't never had this hard a time removing pins. Any tricks to get these things out?
