I dont know the difference. The rear sight has red on either side of the notch, front sight is white. Date code looks to be BO and I can barely make out .If you are going to spend that much on a P9S just buy a P7 but what I want to know is dose the gun have combat or target sights thats would be a steal on a target model. I just saw a P9S 9MM with box and in great shape at the gun show 2 weeks ago for 500 bucks out the door from a dealer
The combat sights are just that - fixed sights, while the target sights are a little taller and the rear is adjustable. I took the picture below when asking about the differences between two slides, but it shows the difference. The top slide has combat sights, and the lower has target sights.I dont know the difference.
