Today I'm bringing the PCCs back out to the range, to try them out with a Woldman suppressor from Dead Air. This is a two-part suppressor that can be shortened a bit if you like, although I will be running it at its full size for maximum effectiveness. I'm using S&B 150 grain 9mm ammunition, which is subsonic. This means there is no supersonic crack produced, which is a sound that cannot be removed by a suppressor. The questions are, how will the different guns handle being suppressed? I have a CMMG rotary-delayed AR, a Kalashnikov USA blowback KP-9 AK, and a roller-delayed H&K SP5.
