Glock 21 vs. 30 barrel compatibility?

    I'm thinking about trading one of my Glock 21s for a 30. Will my Bar-Sto barrel that fits in the 21 also work in the 30 or is the 30 completely different? I don't care that some barrel would stick out past the muzzle. I'd use it for practicing with cast bullets.

    Or is it no big deal to shoot hard cast lead out of the 30 with the stock barrel?

    Here is what Glock has to say. The shading is for my purposes only.
