My first handgun was an FM HighPower, licensed by Browning to be manufactured by and for the Argentinian military. Fit and finish weren't as good as the real Browning but form and function were identical, as far as I could tell. It lasted me several years of VERY heavy use/abuse, finally wore it out. Had it re-worked and sold it "as-is" for just a little less than it cost me originally.
And that was a copy, not the real deal.
I'd say go for it.... I now have two H&K USP's, 9mm and 45acp, and love them but the HP has lots going for it. Great design, tons of spare parts and mags for it, and rock solid in it's function. There are other guns out there worth looking at but the HP is a classic, everyone deserves at least one in their life. You can rely on them when it really matters and never need fear having problems getting it fixed or finding mags for it.
