Just confirming, if I have a suppressor on my KUNA, (which I just ordered one), You don't have to buy rounds that are labelled sub-sonic right? If I already have boxes of Federal Premium 9mm Luger 147 grain, with a velocity speed of 976 fps at 25 yards, and 953 fps at 50. That is considered sub-sonic right? Anything under 1000 fps is considered a sub-sonic round and safe to use with a suppressed handgun and/or PCC?
Thanks in advance.
