your three way is fine... you say you've fitted the Blade trigger yeah? well if you think about it, the blade trigger reverses the way the three point runs (Back to forward, instead of forward to back) anyway, with a standard 45 frame and trigger, you dont get the hissing, thats because the 3 point is running the right way.... the blade trigger reverses the rod and three way, so the excess gas is vented instead of used in the LP hoses.... its ifne, and it happens... mine hisses aswell mate, but as Jahlad said, a good lube wouldnt go a miss....
