The CCI standard is listed as being 1050 fps and the speed of sound in our area is supposed to 1070ish. Most times that ammo is supersonic in my CZ. There are days that it’s not. That’s determined by temp and other weather factors. Also with a suppressor your first shot will be louder than the subsequent shots. It’s called the “one shot pop.” I’m guessing that the 02 has to be burned out of the suppressor to be as quiet as possible.

One thing to know about suppressors too is the back pressure makes your guns very dirty, very quick.
