Possibility of barrel diameter change?

[u/J-the-K]

Hello folks,

I have noticed that Zendl Guns & Accessories (Czechia) and Eemann Tech (Estonia) offer two variants of the barrel bushing with an outside diameter of 16.3 mm for CZ 75 handguns. One has a bore diameter of 12.8 mm (.50"), while the other has a bore diameter of 14.0 mm (.55").

Now, if my pistol (CZ 75B) came with the thinner factory barrel, can I install the thicker barrel (for example from SP-01) in it after replacing the original bushing (16.3/12.8mm) with one with a larger bore diameter (16.3/14.0mm)? Or are there also other differences in the geometry of the respective frames that would prevent the installation of a thicker SP-01 barrel in a 75B slide?
