Aubie, I took everything off the slide except the loaded chamber indicator. The sights were no big deal to me since I have a sight pusher, but if you don't Tripp will remove and re-install them for you. I'd use one of the tutorials on this site to remove the extractor and firing pin assembly prior to sending it. Then when it returns, make sure you blow all the bead blasting media from the channels prior to re-assembling.
