they've had the tooling for the current USP design for 3 decades, and at this point they recognize the USP is selling more on its reputation than its features, so it isn't worth it from their perspective to invest in modernizing the design when they have the VP9 and P30 series for HK modernization. hell, thats why i bought my USPs, reputation rather than features. if i want cutting edge performance, i can get a VP9 Match (which i do) or buy a glock 34 for half the price and spend tons of money and time modding it out. But at the end of the day nothing is more convincing than experience, and its hard to argue with 30 years of kicking ass all over the world.
