+1 for the limcat magwell! Just put one on my chaos and I went the route of clearance on the magwell side, put it on sharpied where it needed clearance, little dremel action and it fit up rock solid. Just ordered another for my back up gun as well. Pt is said to be releasing a similar magwell to limcat that will require no fitting but not sure on eta of that one. Atlas is making one later this year and Akai offers one as well that is available now. I think Dawson would be smart to make a new insert with the convex radius as it does work very well on metal grips.
