i actually had the gun in my hands. Well soon as i can measure the bolt stroke for the gun i can start researching stuff. excuse my ignorance but whats a pilioted solenoid valve? Yeah i kinda observed that the pgp grip is small. Time to modify a frame to fit it i guess. hopefully my shop teacher can show me how to solder brass....really well:-) Oh well time to do a bunch of research. Does the idea seem fesible? Is it worth my time to make it be able to take cocker barrels?
