Well, they're expensive, often seen in 007 films, and very difficult to fill to their designed capacity of ammunition due to lack of pre-bans. Magazine release is weird to me, don't like the little speed bump inside the trigger guard. Maybe I'm just too accustomed to Glock, 1911, Sig.
And what's up with Pierce Brosnan's funky holding-the-wrist shooting technique in the latest 007? Just more Hollywood fakery, I surmise, but it upset me every time I saw that. Didn't know whether to laugh or mutter expletives under my breath. Notice that Bond ends up killing more people not with his Walther but a 1911.
