Without a doubt the HK P7m8 is the finest handgun currently made. Reliability, durability, accuracy, saftey. You can get other guns cheaper but nothing else comes close in terms of the overall package.
The P9 is also an interesting gun. However, the gun has some problems. The saftey is a little awkward, the gun doesn't wear all that well (although, my example was a police trade-in with many, many shots through it). Also, the gun isn't very reliable with hollowpoint ammunition and the double-action trigger was too long. On the flip side it is very concealable despite its length. The accuracy was phenomenal, the grip perfect, and the single action trigger was SWEET.
