Incorrectly regarded as goofs: Bond uses a Walther PPK pistol throughout the movie. If Quantum of Solace is set immediately after Casino Royale, Bond would still be using a Beretta, as Q Branch is yet to have assigned Bond the Walther PPK. However, there is no reason an MI6 armorer could not have switched Bond from his previous Walther P99 to the PPK before he shoots Mr White at the end of Casino Royale. We do not see his sidearm, only the H&K UMP he uses to kneecap White (which he still has in Quantum). He could have had said PPK on him the whole time.
