Re: sand blast
throw it in a blast cabinet after disassembling it, I normally pull the bolt and all internals out and only blast the barrel, and receiver/mag tube. Blast until all the old Parkerizing or Bluing is gone and its a dull finish. Not sure if you are prepping for some form of paint, but if you are, make sure there is a nice even dull finish, then make sure you get all the excess media out prior to spraying.

Re: sand blast
And don't use sand. 120gr AO @40-60psi should work. I'd probably tape over the staked on shell ejector and shell latch thingies. Plug the mag tube at both ends.Plug the barrel at both ends ends. Tape over or remove sights. Disassemble the bolt completely.

Re: sand blast
just remove the bolt and polish it, dont bead blast the inside of the reciever, and if possible use dow rod to plug tube and barrel. or the inside of the slide arm, smoother the better

Re: sand blast
Remove all internals as noted above and wash thoroughly with solvent followed by a rinse in laquer thinner. You want to keep your media as grease/oil free as possible. Mask off the ejector as noted. You can damage it by overzealous blasting and you can also kill the temper of it by building up too much heat.
I prefer to use the cheap rubber stoppers you can grab from the hardware store for plugging mag tubes and barrels.
AlOx is good but I prefer a product called Starblast, a good bit cheaper and does just as well.
Air pressure is critical, your first impression is more is better. But that is not always the case, you want just enough pressure to remove the finish efficiently and leave the texture you want. Too much pressure and all you do is wear out your media quicker.
I like to run my nozzle pretty close to the surface at first. (2-4") to hog off the existing finish then back away from it (8-10") to even the finish out, a buddy of mine calls it "Washing the Finish".
