I have an M&P Pro CORE 9mm. I just had the barrel done (AlTiN) and I want to know if I decide to buy a regular FS M&P 9mm, if I can keep the AlTiN barrel from the CORE, and put it in the new FS M&P 9mm then put the black stock barrel into the CORE and be OK?
Maybe this is a better way to ask...Is there a difference in the 4.25" 9mm barrel in the Pro Series CORE and the FS M&P 4.25" 9mm (non-CORE)? Can the two be swapped with no issues/differences?
