I've owned several USPs in various caliber flavors (all variant 1) and several Glocks in various caliber flavors. Both are great pistols. I didn't read through this thread, but the Glock price seems steep to me, but that's probably due to the color of the frame. If he sticks to his price, the HK is a better buy price-wise. Both are very reliable pistols, but what the Glock has going for it over the HK is the over-abundance of parts (both OEM and after-market) and cheaper magazines. Your best bet is to have your friend let you shoot them and chose the pistol you like/shoot best.
