HK USP tac barrel

[Waylander]

Will a tac barrel work with a standard USP or do you need a different slide?

[Mauser KAR98K]

Will work in standard USP FS. Make sure the tac barrel has the rubber O-ring.

[Waylander]

Sweet. If you want a silencer you have to install the taller sights too, right?

[Talon167]

Well, you don't have to. But if you want to clear the silencer, then yes. I prefer Heinies.

If you are talking USP FS, you will also need the tactical guide rod and spring if you plan to suppress without ruining your pistol.

Thanks that's good info to know.
I don't plan on running a suppressor at the moment but curious about what I would need.
