MP7 is terrible. Okay, that’s hyperbole and second hand info. But it only has a following because it’s forbidden fruit. It can have AP rounds and is more compact than an MP5, but that’s where the advantages end.
The MP5 has been so successful, in part, because it is so controllable on full auto and is very quiet as an SD.
As a semi-auto, the MP5-clone is not much better than any other 9mm carbine.
But I think PCCs are underestimated. They allow easy shot placement and have much lower sound and overpressure than a rifle. Take advantage of the shot placement and it won’t matter that you don’t have a permanent stretch cavity. T-box shots are lights out. Or, just look at the messed up “defensive” shooting a couple years ago where a guy trying to see his kids at his ex’s house (who were his that weekend) got shot with one round to the chest from a Ruger PC Carbine. He was sadly gone in a moment. There’s a video, but I don’t care to dig it up.
There are good reasons why rifle caliber carbines have mostly replaced PCCs, but that doesn’t make PCCs bad.
I’d love to see some ballistics gel testing with the LeHigh 68gr +P defender ammo from a PCC. The Xtreme defenders do better the more velocity they have, and I bet the 68gr from a 16” barrel would be screaming.
