Spent over a year diligently saving up to get this baby, and now it's finally in my grasp! I was torn between this gun and the USP, and I ultimately chose this one. What sold me on the gun: -The grip fits PERFECTLY into my hands. Also very nice sandy texture. -Larger, more flush mag release compared to USP. -Picatinny rail, as opposed to the "You suck and we hate you" proprietary rail. -Very sexy design, unlike anything HK has produced before (P30 series notwithstanding, since it is taken from that design). It honestly looks like a shark. -The 50,000 rounds with only 2 malfunctions report. (Source: http://pistol-training.com/archives/4027 ) It still has some time before it can be judged with its big brother USP, which was reported by a former SWAT member to have 4 malfunctions between 160,000 rounds. (Will add link once I find it again) -More concealable than the USP, due to it being thinner and lighter. -Longer sight radius. My complaints of the pistol so far: -Slide release isn't as large as the USP. -The 'round in the chamber' indicator isn't very noticeable. -The slide isn't as buttery smooth as the P30 right out of the box, though that may change after a couple hundred rounds. -The trigger on HK45 is ok, but not nearly as smooth as my uncle's match trigger on his USP. Taking it down to the range today. Will post results in a bit.
