I just got a bunch of 9mm 124 powdercoated bullets, have a bunch of 9mm to shoot them in, but was wondering if anyone has shot these type of bullets in the mpx?

I don’t know if it is comparable but, I put a bunch of 135 grain TC Blue Bullets 9mm handloads though a buddy’s MPX w/ no ill effects.

I've put a metric ton of 147gr Black Bullets International thru my MPX with and without a can mounted. Not a single problem.
