There may be differences in terms of how those parts are put together with allowances for fitting but a gun from one company should be pretty much interchangeable with a gun from another company.

Parts from a Chevy won't fit a Dodge or Ford. The blueprints and parts for each vehicle are entirely different. They're only the same in terms of general appearance which could be said for almost all semi-automatic pistols as well.
