Threaded barrel

Will you be offering an accessory threaded barrel?

Would this pistol work well with a can?

Yes, it would work with a can, but the thread would have to be left-handed. Any work with silencers would have to be done out-of-state since they are banned here in MN.

As far as accessory threaded barrel - I would do it if there is a standard silencer out there offered with a left-handed thread.

Hey Arne,
I know I've bugged you about this already (and you seem convinced it won't work) but I just received my first suppressor ... and since it's primary host is a Sig 226 I have a piston to accept M13.5 x 1 LH.

If you ever make a trip to Wisconsin with a XR9-S threaded in M13.5 x 1 LH we can test it out!

I have tested clamp collars that simulate the mass and rotational inertia of a can and it stopped the barrel from turning, so the slide would not cycle completely. I have high-speed videos of this. The can would have to idle (spin) on the barrel in order for it to work

Any idea why PX4 doesn't have the same problem?

The PX4 is a much larger gun than an XR9-S and has room for a lower-angle unlock cam, if it is similar to my Beretta Cougar. It believe is possible to re-design this part of the XR9 series of guns to accommodate suppressors.

What I find funny about the video is he used two suppressors - one that unscrewed, and one about to unscrew!

Yeah . . . he used right-handed threads, so it didn't get too tight. Do you think it would get too tight had he used left?

Ah well, thanks for giving it some extra thought!

Right-handed threads would eventually unscrew. Left-handed threads would self tighten quite a bit - you would need some good tools and good leverage to get the two apart.

Detachable camera lenses used to be screw mounted until bayonet type mounting made for quick mounting / unmounting. Why isn't the same thing done done for suppressors / silencers?

The big difference is that the diaphragms don't torque the mount tighter or loser. Modern lens systems (i.e. last 30-40 years) have bayonets that lock into place to negate that issue. No amount of torque (assuming that you didn't break something) is going to tighten or losen the mount since there's another part interfering.

This gun, if I read things right, has a rotating barrel. No matter what you do there it would tighten or losen no matter what you do. A camera doesn't rotate it's mount as you shoot a frame.

I believe that Gemco did this and have a patent on their method of quick-connect.
