Well I'm glad I can legally purchase a .45 ACP 1911 style handgun to shoot various metal silhouette competitions at my Australian military based firearms club. One comp has shooting knock down metal targets to a hundred metres (or sixty? I forget?) and also closer ranges of course. I've shot it only once. With my .38 Super. Normal not target sights. I hit a few. I thought it was pathetic. But ended up sort of average in relation to othercompetitors.

To shoot this properly a good revolver, single action trigger, with a good dot sight or scope I think.

Another metal silhouette is a rapid fire five or six knock down targets. Timed. Good fun.

The IPSC comp, not sure if a .45 is permitted?

Apologies, a bit off topic.

Firearm laws rarely make a lot of sense, whether Australia, France or the USA. Often they are designed merely to restrict,control, that is the only logic.
