I voted "yes", for a variety of reasons.
To be fair, one must consider that what you pay for is not the actual physical worth of an item/firearm. The cost of machinery, design engineers, testing, employee pay, etc. is why automobiles, aircraft, weapons (or whatever) tend to have such high values in relation to cost. HK spends large amounts in research and production considering that they equip many military organizations with small arms (and larger caliber weapons as well). The current small arms they sell are only a small portion of their market, and they, like Mauser, Colt and many others, sell small arms to the private sector and get small return for their overall business.
I think that while there are fine quality firearms available on the market, that HK pistols are worth their cost. HK set out to replace the aging inventory of small arms for the Bundeswehr some years ago, and instead of simply making replacement designs, they also meant to compete or supersede many very high quality military weapons on the market. Few even realize one of the premier .300 Win Mag sniper rifles in the world is an HK (not offered for private sale) and one of the best battle rifles in the world is the G36, also the platform used for the considered replacement to the M16/M4. In relation to pistols, the SIG P226 and Glock pistols influenced the designs of the USP. As a U. S. servicemember, I have fired all of these, to include the US issued M9 and M11 (and M1911), and I think that HKs line of USP designs are at least equal, if not superior to any of those designs. In order not to set off a fury of "mine is better" I won't list individual names, and why I think the USP is as good or better, but if I had to chose a sidearm for military use, I would say the USP (in whatever caliber you prefer) is an outstanding weapon, and might even be my number one choice. HK has been known for cutting edge military grade stuff for almost sixty years now, and that's another factor when you look at cost. I do not own an HK (I have a P228, which I love), but have thought often of trading for a USP compact. I've never been much of a polymer receiver fan, but for military weapons, they make a lot of sense.
I do not want to detract from any manufacturer, all of the high quality ones fetch pretty hefty prices these days. I feel that you get what you pay for with an HK, and believe that all of their designs are worthwhile.
Anyway, my two cents worth. I have to add a personal bias; my last name is Koch!
