Just picked up a "new" USP Combat 9mm that came with Night Sights , LEM , Jet Funnel Kit and two 18 round Jet Funnel mags that I bought from Kjergaard Sports through Gun Brokers. Problem is when I got it home from my dealer, I discovered it has a AF date code , 2005. That means the night sights are already 7 years old and going dim. Ad never said any thing about being "new" old stock. Not sure if they have changed the design much between 2005 and 2012 ? Having old night sights does bothers me. What would you do ?
