I'm in the process of installing an Ed Brown 2-piece magwell on my STI Trojan. There is a slight gap between the magwell and the bottom of the frame. I'm guessing it won't be very noticeable once the grips are on, but I'd like to tighten it up some if possible. I'm thinking since it's a two piece maybe I can just remove the chute and file down the bottom of MSH to effectively shorten it? Has anyone done this? Any other tips? Trying to avoid any welding or refinishing.
