I have a M&P 40 S&W 1.0 with a 4.25 barrel. I bought a 1.0 9mm 4.25 barrel and 2 x 9mm 17 round mags.
Now I would like to get another slide for my gun so it would be quick to replace one barrel with another by simply replacing slides. The problem is I can not find the slides anywhere.
Any suggestions where to purchase the 9mm slide?

Thank you
