I own an M&P9 Performance Center 1.0 and an M&P9 2.0. I know the magazines are interchangeable between the 1.0 and 2.0 guns. What about the slide assembly (barrel, recoil spring, etc.)? I ask because I much prefer the grip feel of the 2.0 to the 1.0 but my 1.0 has a ported barrel, threaded barrel, and supports mounting an RDS.
