Will this slide fit?

[Fmantee]

I have an M&P 9mm 1.0. Will a slide from a 2.0 fit it?

[Saudade]

Fit, yes. Function, well maybe. The slide locks are different so therefore the notches are different. Some folks have reported the 1.0 slide lock can catch the 2.0 slide notch. Others have had to modify the slide lock.

Of course here we talking and full size 1.0 and full size 2.0.
