Polishing a glock barrel is really easy and only takes Mother's Mag Polish and a terry cloth.
There are walk-throughs on GT that make it really really easy.
you also dont have to go crazy being you never see half the barrel when it is in use. though, I opted to just do the whole thing to make it uniform.
And I am really really wanting a 17L now!
