The “Shooter’s Choice” writeup specifically addresses live rounds ejected from a rifle and failures-to-fire in percussion or cartridge firearms. I believe it has been applied to other situations in which a shooter has “engaged” a target (attempted to shoot it) but did not fire a round. The cause of the failure to fire clearly includes outrunning the manually operated rifle, a cap only ignition in a percussion revolver, or a cartridge in any type of firearm that goes “click”.
Since the 1911 pistol is a semiauto there is no manual action (such as levering the rifle or cocking a revolver) to clearly evidence the effort to shoot a target.
One approach would be to only apply Shooter’s Choice to the 1911 when the hammer has fallen on a “dud” round.
For the record I would recommend that a shooter who experiences a 1911 stoppage to shoot the next target in the sequence.
The correct application of Shooter’s Choice can save a shooter from a ten second penalty. I like that.
