I acquired a '93 vintage Witenss Compact all-steel, and found there was a company recall concerning firing pins. Called the company CSR, and lo and behold, I have a brand new firing pin installed, at no cost. I shipped through my local armorer.
The Witness is a pistol that has created very many indecision moments at home for me, as to carrying it, or carrying my BHP! I shoot a variety of NON-PLUS-P ammunition (company suggestion from website), and the Witness just says 'Yummy!', and keeps going. It can be carried in Condition 1, or hammer down for DA use.
Have fun with it, and know that it is designed to shoot accurately, and will send Patriot Injection Modules downrange to where you aim.
