The changes I like to my Loaded are a 10-8 flat trigger,10-8 rear sight(stock trit front plain rear),Wilson tactical thumb safety and VZ Recon grips.
Those were my comfort changes.
I've run it through a pistol class and have shot some IDPA with it, very happy with it.
It loves the CMC power mags.
I replaced the ignition group with a Cylinder and Slide set, got lucky, a true drop in 4.5 trigger.
Some good info on parts here:
