    M11A1, Anyone with one in OR?

    Curious if anyone on here has or has had one of the M11A1 or M11/380s? Just curious on thoughts/pinions or first hand experiences getting one of those running. I debating on starting the Class 3 journey with one, specifically to run the CF-W 9mmA bolt to slow the cyclic rate a little.
