    Default How hard is it to get a threaded barrel on a P7M8?

    I never would have considered this before, but I find myself wanting the Dead Air Odessa 9. And this is their promo material:

    How hard is it to get a threaded barrel on a P7M8?-odessa-9-spy.jpg That is beautiful and I want to be able to do it if I do in fact end up buying this suppressor. Is it possible/practical to get a threaded barrel put on a P7M8? I seem to remember some talk about extending the stock barrel by cutting threads and screwing on an adapter, but that sounds janky to me.

    You need a factory extended barrel. Not common at all.

    Mark McWillis of TROS does the backthreading you are talking about. People used to pay stupid money for a factory extended length P9S barrel until he developed that technique, but if you wanted a .45 P9S set up for a can, a factory barrel (or at least a new over length threaded barrel installed on a factory trunnion) is your only option, there is not enough "meat" to do the work safely.

    I found a factory P7 barrel that had been previously cut/threaded 1/2x28". Sent it to H&K USA for installation. Got it back, took it to the range, shot it, listed it for sale. Bluntly put, P7 series (unless we are talking K3 in .22LR or .32, 9mmk the can is too big) suck for suppressing. Looks cool as all get out, but loud. LOUD. That pop when the gas system vents is atrocious.


    Save your money.

    Sadly TROS might be in hot water so Tornado might be the only people that could do it.

    I hadn't heard......

    Agreed, Tornado Tech can and will handle anything Mark does or did. I have used both, no problems either way.

    Can you expound upon this before I place an order?

    It’s sucks because I’ve worked with him in the past. I have two AR15 3-Lug barrels that have worked well.

    HK had long barrels at one time. I had one put on my P7. When I received it from them I removed the pin and drifted out the barrel, cut it to the length I wanted, threaded it, and then reinstalled it. I’ve never fired it suppressed, but it works fine functionally.
    That’s been many years.

    I think that is true generally, but I have both a P7 and a P7M13 with HK factory threaded barrels (still looking for a P7M8) and the Vaime suppressor that was engineered specifically for the P7 series. It is looooooooong. In fact, the P7 + Vaime suppressor is longer than my MK23 + B&T suppressor. But there is a reason for the length. To get the proper level of suppression, they had to have a certain total volumn, and since HK required the suppressor to work with the standard P7 sights, they were limited in how "fat" it could be, so the only way to get the needed space was to make it longer. It looks odd, but it works great. I don't get any gas blowback in the face.

    Here's a link to a discussion of the P7 series as a suppressor host. Please note my comment (#21) and the response from G3Kurz (#29)

    That said, I don't know how the Dead Air Odessa 9 would work with a P7 series pistol.

    "I know what you're thinking: 'Did he fire twelve shots or only eleven?' Well, to tell you the truth, in all this excitement, I've kinda lost track myself. But being this is a HK MARK 23, the only offensive handgun in the world, and would blow your head clean off, you've got to ask yourself one question: 'Do I feel lucky?' Well, do ya, punk?"
