What guns have a threaded bbl with 1/2" x 20 pitch?

I have a Tec-22 with a threaded bbl and I was wondering if there are any other guns that have the same threads so I can buy parts for it. I am looking for a flash hider or something to hang on the end of it just for fun.

1/2X28 is about a coarse as I've seen. 1/2X20 is pretty rare.

The Tec-9 uses the same thread and Tec makes a fake suppresor for them. Should screw right on.
