for the last time...
for a really good silencer solution phone the chap at Woodchucks silencers and get a slip on 1\2"UNF adaptor.
I prefer this solution so that I can then screw on any silencer I want.
Contact Charles Ellis (011) 476-3192 [firstname.lastname@example.org].
He also makes silencers.
You can then screw on any silencer you want.
The Manders silencer from NZ is really small and really effective....I love it...got it from City Guns in CT [R260¤¤.
