Great question! to which there are two answers:
For your forty five, the common and generic answer is as vague as your understanding. It's basically "knife-fighting range."
More relevant to rifles, but important to ballisticians, is the formal answer, and I'll walk you through an example. Let's say you've put down your 45 and picked up a new bolt gun to go deer hunting. You have a load picked out and know about what the ballistics of the cartridge and the ballistic coefficient of the bullet are. Deer have a vital area that's about a four-inch circle. You take your chronograph, your laser range-finder, and your ballistic computer out to shoot and sight in your scope. At what range to zero the scope? Many pick 100 or 200 yards, but the more advanced way to do it is figure PBR. You want to be able to aim dead-center on a target and hit it at any reasonable distance. You do a lot of figuring and shooting, and you zero your scope to distance X so that you're within that 4" circle all the way out to distance Y. Distance Y is your PBR, and if you do this, your shots will be at the bottom of the circle at that range, but no higher than the top of the circle at any intermediate range. That often leaves you with an odd number when talking to buddies, and they'll look at you funny if you tell them you're sighted in exactly 2 1/4" high at 100 yards, but you can smile knowingly while they're scratching their heads. PBR for a typical deer rifle may be somewhere in the vicinity of 175-325 yards. Note that it's dependent not only on the gun and the load it's firing but also on the target. A 30-06 shooting the exact same 180 grain bullet at exactly the same 2700 fps will have a longer PBR when hunting elk (6" vital zone) than when hunting deer (4" vital zone), and could be sighted in differently. Hope this made sense to you.

Since most handguns shooting occur at ranges of 7 yards and under, point blank would be less. I would say it is the distance you can hit a 8x112 square, consistently, without using the sights at about 3 yards.
Pretty much limits you to shooting from the waist since that short of distance can be covered by an attacker in just a second or so.

The Hollywood version of point blank range is contact distance. However WDD has correctly related what point blank range really is. Hollywood simply and incorrectly used the term so often that contact distance is what most people think of when they hear the term.

Within 3 feet of the target is point blank range.

With in 3 yds is point blank range. And pbr is the same for a 45 as it is w/any other firearm.

My thought?
25 yds or less. Will be considered “point blank”. Using your terminology. Regardless if firing a pistol or a rifle. Caliber is a non issue. The law of gravity impacts all calibers equally. Anything over 25yds? Point of impact is determined by the specific caliber,
type of bullet and the powder and grains used .

I've always heard that point blank is putting the muzzle of the gun on your intended target and pulling the trigger.
