I would really consider selling my Gen4 G19 and getting one of these new M2.0 Compacts. I do have a new 5" FDE M2.0 in .40 and a 1.0 40c. Got quite a few goodies for both.

I'm pretty sure I'll be able to use the "New" M2.0 compact magazines on the older 1.0 compacts. I could see my 40c go from a 10 round mag to a 13 round mag. I do use the full size 15 round magazines when I CCW my 40c from time to time.

Nice Job S&W!
