147gr 9mm ammo that is subsonic in KT SUB2000 CQB...

[TED]

The KT SUB2000 CQB has a 4.25" barrel and a large suppressor.

I just bought one.

It is my belief and hope that most if not all standard pressure 147gr will stay subsonic in that 4.25" barrel.

Does anyone know of any that is NOT?

Thanks.

Ranger T RA9T and every 147gr ball (factory and otherwise) I’ve tried stay subsonic in several suppressed PCCs in my social group including longer barrels. I think 12” is the longest any of us have, with the remainder being like ~8”. I’ve tried some other 147gr defensive ammo, also, but I don’t remember exactly which, and it was subsonic, also. 135gr ball (again, don’t remember the brand) was sometimes subsonic, sometimes loud, even in a G19. Basically pew, pew, PEW, pew in the shortest suppressed barrels.

We shoot quite a bit of regular 147gr ammo, suppressed, in training analogs of our 5.56 guns. Its the same stuff we use in our pistols, meant to duplicate our carry loads.

In a 4 inch barrel pretty much any standard pressure 147gr should be subsonic. I've run quite a few different labels through mine, haven't found one yet that gives the tell tale "crack".

147 gr Ranger and Gold Dot, both standard pressure are subsonic out of my B&T GHM9k which has a similar length barrel as your Keltec.

You should be fine.

Good additional discussion here.
