The anecdote goes that for the original version at WDW, Imagineering expected the spinning part of the attraction to be the big draw (hence Buzz Lightyear's Space Ranger Spin), as it had been in the Roger Rabbit Car Toon Spin attraction at Disneyland which had just opened. When they realized the shooting was the big draw instead, and most people were just using the spinning to adjust their ride vehicles, more emphasis was put on the shooting technology and the guns were made removable from their holsters (hence Buzz Lightyear's Astro Blasters).
