I've got 3 of the P7s. I think they are about the greatest 9mm carry gun out there, with the only drawbacks being the price and difficulty getting mags and replacement parts.
Very accurate and (for me) the most natural pointing pistol I own. The p7m8 has a heat shield in the top of the trigger guard. My older ones don't have this, and they get pretty hot after 70 rounds at the range. Also, due to their gas system they don't run very well dirty and need to be cleaned after 300-600 rounds, depending on ammo used. I wouldn't choose one if I was going into battle, but for a concealed carry gun that I can clean regularly it is a great gun.
