Rip,
1. I have one on order from CGW right now. I will update my grip size thread below once I have it in hand and will post up some pictures. I opted to have CGW perform the Mod as he refinishes it too.
2. I experience the same with my 97BD with round nose bullets. I think the bullet profile is hitting the underside of the slide during insertion. I don't have the problem with the SWC's I'm currently reloading. It only seems to be difficult with a full 10 rd mag, if I only load 9 in the mag it's easy to insert. I think you may be better off getting heavier mag springs. I think it will help ensure they stack in the mag properly during loading and feed properly during cycling.
Cheers,
Toby
