.45 ACP-partly truth and partly fiction
You are correct when you say most "off the shelf" .45 ACP lacks stopping power.
Someone with sufficient experience with the round and the guns that fire it, however, can safely engineer handloaded ammunition which will knock down and demolish a 55 gallon drum full of wet sand at 25 yards.
The issue is how much of the kinetic energy of the round can be transferred to the target on impact.
A properly loaded .45 ACP round hits a human-sized target with the force of a lead basketball moving at 300 mph, and, as you've pointed out, the bullet is subsonic and usually stays in the body, which is important in home defense.
