 HK USP expert chambered in 9 millimeter. This is a large model with a 5.2 inch barrel. You're looking at 15-16 hundred bucks in today's market, but it's a nice handgun. The USP models are very well regarded. The single action trigger is pretty amazing right at four pounds with a reset that is fairly short. Nice trigger pull, nice tall sights in the front. It's a rated black rear sight.
