I got my Retro Valve about 2 weeks ago and it isn't very "reactive." At first I thought it was good because it was shooting about 2-3 shots on every trigger pull, but I realized my field strip screw wasn't tight enough. I tightneded it and I had a stiff trigger that wasn't anywhere near as good as other retros Ive shot (I even used my friends adjustable tank on my retro.) I did a search saw stuff about a shorter on/off. Is that what I need? I have a classic powerfeed mag, with the stock body rail, and stock trigger frame, so the tolerences should be really good. How do I get the shorter on/off? Thanks for the help.
