Forgive me if this topic has been beaten to death over the years, but I just noticed it for the first time while watching Return of the Jedi a few weeks ago.

In the battle scene on Endor when Han Solo and Lea are trying to breach the selaed door to the Imperial bunker there is an inconsistency in weapons Han is holding. IIRC its between when Lea gets shot in the shoulder and Chewie shows up in the stolen walker.

One scene shows Han holding one pistol ... the scene cuts to a shot of something else (IIRC either the stolen walker or approaching Stormies), and then returns to Han holding a different pistol.

Again, sorry if this is old news :-).
