Corrected entry: In the final fight, in the house in Venice, a bad guy shoots a nail gun at Bond. Nail guns use safety catches that prevent them from firing unless pressed firmly against a surface. Although this safety can (on some models) be pulled back to allow a nail to fire, this is never shown to be the case, and since the gun was picked up from a construction site it can't have been modified by the bad guys.

Correction: Not all nail guns have these safety features. At least in Holland these are available, and so presumably also in Venice, which is also in Europe.
