I have been shooting an Edge now for about 8 months. I did not like the grip at all, but avoided stippling. I rounded out the edges on the grip and threw on some of Eric's grip tape. It is a totally different gun. Try the tape first, its only $25 versus $100 for a new grip.
I use a STI solid metal guide rod, and it feels better than the recoil master. It wasn't that expensive.
Good luck on the sights. If it is a duty gun, get used to kentucky windage or go with the bomar.
