Best 9MM subsonic for RPB MAC

Recommended Posts

Have an RPB MAC that won't feed Federal 147.  I assume it's because of the squarish shape of the bullet not being able to slide up the feed ramp. Shoots all 124 gr supersonic fine.  At any rate, what have you guys used for your factory subsonic rounds?

Buying another Mac in 45 should solve your issue! Lol Jk have you tried sub sonic 124 grain? I’ve used American Eagle Suppressor 9mm Ammo that is 124gr I think that’s pretty much the name on the box an it ran in my m10 seems to stay subsonic

I've shot it in suppressed pistols but I thought it was discontinued now?
