Has anyone tried the suppressor ready P-09 in the IDPA box. I did a search and there was a post asking the question a couple years ago and the only answer was that "threaded barrels aren't legal in sanctioned matches." If that ever was the case, it is not reflected in the 2017 rule book.
The CZ-USA website states 8.8 inches for the length. The IDPA box is 8.75 with some tolerance (sometime). Again, has anyone tried it?
