Well, OK....it's a Bauer copy, but still, was a fun Sunday morning project:



Running wet & wiped with the Ocelot Micro, I expect dBs in the mid 120s. It's a bit louder with white lithium instead of water, but I think still under 130 with 50 gr FMJ loads.

I enjoy the challenge of finding ways to thread the unthreadable. This .430" OD barrel got counterbored and threaded 3/8-40, for which I made an adapter extension of 17-4 treated to H900



I left the OD a tad large, installed the adapter (red loctite on this one, doesn't need to come off), then threaded 1/2-28.



Could be a tad smaller with a pill bottle can I suppose, but much better suppression out of a 3" five baffle can than a 1.5" baffle-less type. While much louder dry & unwiped, it should still be hearing safe, as it meters 133.51 shooter's ear on a pistol with .22 LR 45 gr. subs

That's pretty darned cool right there.

Bravo.

Delightful solution to coupling a small barrel to
½" x 28 'format'.

Your nicely machined adapter is the way to go
for attaching a can to a Walther PPK by removing
original PPK barrel and inserting a PPK/S longer barrel
via the tools used to replace Makarov barrel.

Nice presentation.

Thank you.
