USPs don't sell very well, at least around here. MY LGS has a lot of HKs buy rarely a USP these days. I tried a couple USPs before they but did not like them and shot the HK45 and P30L a lot better so that are the ones I bought. With the USP you are stuck with the grip you get while the P30 and VP9 have changeable back straps and palm inserts. Your best best bet as usual is to try out whatever you are considering if possible.why do you believe this is true? Have you handled them side by side? I can't find a USP in my area.
