I have a VP9 one. I bought a threaded barrel for my VP9 (I think factory, but it might be RCM) but bought a VP9 tactical shortly after (I'm a sucker for the "tactical" roll mark).
Also on my glock 17's I've had good luck with Zev barrels (I think I own quite a few of them). Surefire barrels are good, I had some lonewolf in the past that worked but had an occasional hiccup while suppressed. Though stormlake makes a good barrel, I feel they extend too far from the front of the gun. My blacklist barrel has a nice finish, and comes with an o-ring.
