Just don't ask them to load your magazines.
actually, the whole backwards loading thing started from a marketing advertisement error a few years ago. the hired photographer was required to take a picture of the new P2000 pistol, which he did.
however he did not fully understand how to load the magazine, and subsequently put them all in backwards. now the picture, (front page for an HK catalog) has become the inside joke to many HK owners and hecklers alike. (no pun intended)
i have owned two USP pistols and over the last few years, then have proven to be nothing short of amazing. and no, the magazines are not any easier or harder to load than a glock, sig or S&W.
i cant wait to pick up a p30 or maybe even HK45. i haven't decided yet
