Same recoil spring/guide rod assembly for M&P 45 full size and 2.0?

[asilcot]

S&W website shows part # 391690000 Recoil Spring and Guide Rod Assembly is fitted for full size M&P 45. Does not say anything about 2.0. The compact part states not for 2.0. Should the full size recoil assembly fit my 2.0 4.6" 45?

I called S&W and they confirmed that as the correct part number. While they did not specifically say that 1st gen and 2.0 are the same the fit came down to barrel length and whether it was full size or compact.

I'm pretty sure they're interchangeable, but ask THIS guy. He is happy to answer questions and will know for sure.
