9mm to 40?

[scubie02]

can the 9mm be converted to 40 by swapping the barrel and spring, the way 40 and 357 sig can be swapped for many guns?

[scubie02]

ahh, sorry, the search function seems to indicate this doesn't work, which is what I suspected

You are correct.

Correct, the slide on the 9mm is only bored for the diameter of the standard 9mm barrel. If it were a .40 or .357 you could go the other way, as you'd end up with a 9mm barrel with thicker walls.
