I think the vid mentions the cost of rounds... $40 each.
Haven't bought any new firearms recently. My Walther pistol and CZ
Scorp, both 9mm, are pretty "quiet" with the suppressor affixed. The
Walther has a really nice trigger, and I'd rank the pistol the
second-best I've ever fired or owned, after the CZ Shadow SP-01.
That's the only one I've regretted selling.
