I've been thinking about upgrading my gear box. I'd like to get one of those reinforced 7mm bearing ones. I know that they increase rate of fire and are energy saving but do they do anything else? Would like to know if its worth the money to get one, and which one is the best to grab.
it might be that shimming wasn't done right..
For your G18 check out Norca, he's out of stock right now, but he should have some in by thursday at the latest. I have the G23f(just compact version) and it kicks butt. I have no idea about the upgrading of your gear box, but Jeff at Norca is pretty knowledgable, and he does upgrades and repairs, so if you can't get Vincent to square it away then check him out.
