If you mean the 12" hand guard that comes with the Patrol's 16" barrel then no. The standard hand guard is not wide enough for most suppressors.
If you mean the hand guard that comes with the 11.5" barrel, then it's short enough that it won't interfere with a suppressor (but still not wide enough to cover a suppressor if you shortened the barrel).
