Threaded barrel

GreyHammer · 06-04-2016, 07:40 PM

I actually tried this with a P-08 4" barrel, and the sound suppression was not very good. I was using a YHM Phantom 9 mm and Nielsen device, with this exact attachment configuration. After several magazines, the threading on the retention sieve failed. In other words, the rearward pressure on the coupler cannot withstand the recoil from the slide. It was hell getting the grossly now cross threaded locking device off my gun. I had to use vice grips, and that was that for me. If the locking device was holding for 360 degrees, this might work. But as configured, the locking device will fail. I strongly suggest money not be wasted on this DAQ Coupler. I also had a machinist make a 5/8-11 to 1/2-28 thread adapter.

BTW, a similar device works great on my 10-22.

do they scratch finish of barrel?

No, the barrel tip was not scratched. With emphasis, the adapter will not adequately withstand the forces of the barrel recoil.
The primary motive was to be able to shoot my Lugers in the back yard. I will stick to the SIG 229 and a AR 9 mm upper for that.
