I wish my RIA Tac-10 had regular sights instead of a giant glowing orange orb way out there. A nicer trigger. The one that it came with is OK, and far better than most, but could stand to be lighter. Overall weight coming down might be nice. A Titanium/Scandium gun Something around 25 ounes or so, would be da bomb. Or perhaps a Graphite/Poly framed 10mm would be AWSOME!
The McCormick "Match Prepped" hammer and sear are EDM cut from tool steel and the sear engagement surfaces are already prepped. Meaning, you can get a downright decent trigger pull from just dropping these parts in. Further tuning of the sear spring can drop the trigger pull weight down a little more. You won't get a 2.5lb trigger, but it will likely be very crisp and around 4lbs.
