    Default USP Expert 45 possible tactical barrel?

    I have a USP Expert 45. I want to throw a tactical barrel on it.
    I've looked around this site for a few hours now and can't find the answer.
    Can I do this? I've read that all USP 45 slides are compatible with the 45 frame. I'm assuming it will work but I'd like confirmation.
    Who makes the best aftermarket threaded barrel with LH threads?
    Will have to put on new sights? The Expert sights are kinda tall, so I'm not sure.
    Thank you in advance.

    @Davidsonmd Jarvis has got one, EFK doesn't have one listed. It's doable - you will lose the HK polygonal barrel though and maybe a little accuracy.

    Why would it lose accuracy?

    By virtue of you replacing an HK polygonal barrel with a barrel that has conventional rifling. And I did say maybe.

    You may to able to buy a Elite 45 barrel and have it threaded , but they are very expensive. I forgot the expert and elite slides are a different profile on the top

    Sounds to me like you need to just buy a USP 45 Tactical and be done with it!

    This is a tactical barrel inside a Expert slide.

    Two barrels side by side. Expert on left. Bottom I guess.

    If I read correctly, @majorbanjo was suggesting that the OP just buy a USP Tactical 45. Not to use a Tactical barrel in the Expert.

    Yes, but OP wanted to put tactical barrel in Expert. Just showing it’s a no go if you want the threads. Personally, I’d just get the Jarvis barrel. Someone mentioned the Elite barrel route, but the O-ring would be lost to threading and I’m not sure there would still be enough room. I didn’t pull my Elite barrel to check.

    ETA: I considered a threaded Expert as well so a Tactical isn’t quite the same. I just bought them all. Since I decided I’m going to carry my Expert a bit, I decided against getting a threaded barrel.
