The P322 was completely designed and built by SIG SAUER in New Hampshire and is loaded with premium features, including an optic-ready removable rear sight plate so you can easily add a ROMEOZero red dot optic without the use of adapter plates. The P322 also comes with a threaded barrel adapter making it suppressor ready right out of the box, and with its ambidextrous controls, interchangeable flat and curved triggers, and fiber optic front and rear sights.
