Here is some historical fact on Col. Copper
1961 publication written by Jeff Cooper titled "The complete book of modern handgunning"
Page 101
"Pistol shooting may be divided into two broad classes: sighted and unsighted. Each class has two subdivisions, making four types in all."
The accompanying table shows how it's broken down
Page 102
"It may seem that while most of the sporting or recreational uses fall into type 1, the major practical values will be found in type 2 through 4. Naturally, if sporting competition is conducted to include type 3 and 4, practical and sporting use will coincide. While many excellent performers have chosen to devote themselves to just one of the four types of pistol shooting, no man can consider himself to be a real pistolero until he can excel in all four."
The accompanying series of photos shows Cooper drawing from a shoulder holster to something akin to Bryce [ not quite 1/2 hip, but not quite 3/4 hip ]. He states the sequence should take about .60 seconds

Point, this is the basic type 3 position. It is not for sporting position, except in the sense hat combat competition is a sport. It is used for hitting a human enemy with great speed at ranges where instinct is not accurate enough but real precision is not necessary-roughly 5-20 yards." ------
"First, the pistol is not raised fully into the sight line. The eyes focused on the target, not the sights, for this is unsighted shooting"-----
"I have seen one distinguished pistol shot draw a 45 auto-pistol from a safe condition, fire five shots, reload and fire five more, all 10 striking in a 12" circle at 10 yards, in 4 1/2 seconds--using this position. That's roughly one second to draw one second to reload and 10 killing hits placed in 2 1/2 seconds. It can be done." The accompanying photo shows Cooper in the point shoulder firing position [ one of the skills taught by myself and others ].
Type 4 instinctive shows Cooper once again in the quasi Bryce/1/2 hip firing position. "The eyes are focused on the target, not the sights, for this is unsighted shooting."----
"This is the indoor, arms length, maximum-speed, fighting stance It's hardly precise but it can produce dinner plate accuracy with blinding speed at the ranges which combat pistols are normally used. This is sometimes called hip shooting"
