Well, I put the on off pin and an x-valve on/off assembly into my classic valve. yes, it did make the trigger pull much lighter.

Unfortunately, it resulted in serious shoot down. Can't figure that out.

Anyways, I figure I can either figure that out, or grind the pin down to .712 for my emag valve. What is the best way to grind that down so that there are no burs, or what is causing that shootdown?
