I have a HK USP 40 fullsize. I want an o-ring barrel with the polygonal rifling. Does anybody make these aftermarket? Does HK make one that we can buy?
mainly I just want an o-ring barrel. But I would like to keep the Polygonal barrel.
any suggestions?
I'd really like a threaded barrel, but the PRK says no.
