EDC: SIG P938.
Sounds like you've got it covered. You've addressed the sights and the grip shape to your satisfaction; it's accurate; it feeds everything; what else is there? The new hammer won't do much for you without corresponding work on the sear, and you'll also need a new or modified grip safety to accommodate it. You might want to spring for a complete trigger job, but you don't mention the trigger as a sore spot. Shoot it a lot, and enjoy.
