Not much. Grips, or maybe just a Tyler. Complete internal cleaning and relube, including RIG +P Stainless. Had a few tweaked by Behlert, but I put the hammer block back and went back to a factory mainspring. However, the gun popped primers with Behlert's spring (the original, full length but ground down). I 've bobbed more than a few hammers and ground off the SA notch. I don't bother removing SA notch any more. I have no intention of cocking a gun with no hammer spur, and I just don't care enough about alleged legal ramifications to bother. I have also paid for a polished smooth narrow trigger on a few guns. I may have polished the rebound slide on a few with a Hard Arkansas stone, but with the +P lube, it may not make a big difference.
I have used red nail polish on most of my carry guns.
