rgoberle Posted August 24, 2022 Share Posted August 24, 2022 I am considering getting a 10mm M&P and was curious about swapping the 10mm barrel out with a 40 S&W as an alternate to the 10mm. Does anyone know or have tried the swap. I am thinking the swap should work as long as the barrel length is the same. I am not sure if they changed the outside dimensions of the 10mm from the .40.
