Does anyone know that since Storm lake makes a 10mm conversion barrel for the 30 will the 10mm to 40 s&w conversion barrel also work in the 30?
 
The difference between Glock's 10mm and .45 slides is the breech face width.

The .45 breech face is wider than the 10mm, so if I put a G29 barrel in a G30 slide, it'll fit with room on the sides of the barrel. But if I put a G30 barrel in a G29, it won't fit.

So with that in mind, 10mm conversion barrels aren't meant for .45 slides. However, you can find several people who've had good reliability doing it. Personally, I'd give it a try, but with caution....I have no idea how much, if any, support is lost by going with a barrel that doesn't have contact on the sides of the breech.... If people have done it wit success, then I'm sure it's not a big deal, but then again, I'm not sure that it couldn't be.
