I have a SIG P239 with factory 357sig and BarSto 40S&W and 9mm barrels as well as a SIG P226 with factory 40S&W and BarSto 9mm barrels. Although the BarSto barrels are drop-in, each had to be fitted, all but the P226 9mm by BarSto and that by a local smith. Is it standard practice to fit "extra" barrels so that they sight in with the existing sight adjustement? That is, if I swap barrels, should I expect the same zero, at least at 25 yards?
