Who doesn't love the classic Bond gun?
It's a gorgeous gun with great ergonomics for a one-handed grip. When you go to a traditional two handed grip, the size of the gun is apparent. Even in my little girl hands I feel like there's not enough gun to hold on to. Similarly, I think the size of the gun necessitated using smaller stalks for the sites and it makes for slower site acquisition. Perhaps this would change with more practice, but it's something I definitely notice.
It's really just that a personal preference that I have about all of the pocket guns. For a BUG or in a place where a larger gun isn't possible, the PPK would be my choice.
Oh, and did I mention... this guy likes it:
