I've decided that one of the purchases I make with next year's bonus will be an HK Pistol + Suppressor. I know that I could easily do a search on which Suppressor is the best, but what about which HK pistol is the best?
I know that the USP series have the Tactical variant that will take a suppressor, but do the P2000, P30 etc have tactical barrels? Can I put a USP-T barrel in the P2K/P30 if they don't have a tactical version of those pistols?
I'm leaning heavily toward the P30 because I like the grip (saves me from buying a Hogue slip-on) and I especially like the standard mounting rail on the front, but I don't know if there is a tactical version of the P30 that will take a suppressor.
Also, what caliber is the quietest when suppressed, 9mm, .40 or .45? I'm not tied to any one caliber, the goal of this project for me is to get the gun to be as quiet as possible.
