"Actually, that was one of my favorite movie moments, along with Harrison Ford and the dude in black with the big sword in "Raiders of the Lost Ark"."
That was classic :) I also like in the second movie where he reaches for the gun against the two swordsmen only it's not there this time :)
If you watch the bar shootout in "Raiders", you'll see Indy's Smith N-frame morph back and forth into a M1911 and Browning Hi-Power.
