Do short "K" style cans have less back pressure than full-size?

Is this the same for 9x19 in a .45 can?

I've heard it's not from a buddy with personal experience with that.

Yes, I run my APC 9 Pro with a Ti Rant 45 can and its Hollywood hush hush with my 147's. And I found those cans for very cheap since no one is buying 45 cans these days. Like half price.

I would have thought not. But like PB just posted... we did it, and it works great. I remember the old days reading that 45 wouldn't suppress well due to the large bore. But a WHOLE LOT of old dogma about suppressors was way friggin wrong.

Thanks. I had considered getting an Omega 45k instead of the 9k just in case I ever wanted to use it on as .45 but figured it's already going to be louder as a K and would be louder still running 9mm through a .45 can.

No big deal. Unless I ever get a strike.
