>A Walther PPK 7.65 mm, of course.

There's a good value range of 'PP's: Makarovs.

Actually the best thing I'd give the groom or bride at a wedding is the advice 'don't let the photographs keep you long'.
Practically every wedding I've been to was ruined by the bride and groom being made stand for ages while they got embarrassed and people got bored.
I simply walked away after 5 minutes.
