A friend has a P7 - a very nice, historical, collector's piece. Interesting, but... it's a single stack in a world that's gone double stack for the additional round count. It has the clumsy mag release on the heel, demonstrably inferior to the much more accepted mag release button below the trigger guard. Plus, everyone seems to be going to red dot optics, which couldn't/ shouldn't be done to that collector's item. Time has passed the HK P7 by.
I'm not convinced red dots are useful for a CCW self-defense pistol, but I'm becoming a voice in the wilderness.
