none of these are delayed blowback, they're short recoil. The only delayed blowback pistol I'm aware of is the CZ-52, which functions similarly to an MP5.
How do you categorize handguns?

H&K use Browning type action.
From H&K USA site.
The USP control lever, a combination safety and decocking lever, is frame mounted and quickly accessible, unlike the slide-mounted safeties common on many semi-automatic pistols.
Using a modified Browning-type action with a special patented recoil reduction system, the USP recoil reduction system reduces recoil effects on pistol components and also lowers the recoil forces felt by the shooter. This same recoil reduction system has been tested and proven in the HK Mark 23 pistol developed for the U.S. Special Operations Command. The USP recoil reduction system is insensitive to ammunition types and requires no special adjustment or maintenance. It functions effectively in all USP models.

Short recoil for sure but arn't locking barrel lugs not considered delayed? Or inertia delayed?

My bad. Please ignore my "blowback"

No, A blowback design uses a fixed barrel, such as a Makarov, Whalter PPK, and other such small caliber pistols, but larger calibers (read anything bigger than .380 ACP) generate too much pressure for a simple unlocked blowback design small enough to fit in a pistol, so you either have the barrel lock to the slide and recoil together until the pressures have dropped (short recoil action) or you have the roller delayed blowback action, where the slide/bolt has a pair of rollers forced out into notches in the frame/receiver, this does not truly "lock" the action, but provides enough resitance to slow the action down until the pressure drops to safe levels.
TL;DR short recoil action locks the slide to the barrel and unlocks by travelling rearwards. Delayed blowback does not lock the action, but simply provides mechanical resistance to prevent the action from opening prematurely.
Nope, if you block the slide with the face of your thumb, you're good - though some suggest this for contact shooting, there are ways around turning your autoloader into a single shot that make more sense, but if you lock your thumb over the back of your hand, the sharp edges at the base of the slide will carve right down to the bone. It's not the force of the slide, as such. It's the sharp edges cutting that do the damage. Using the thumb to override the disconnect is an interesting technique, and it's something that could possibly come in handy, but once you've done it a couple of times, there are better things to use ammo for.

Granted you can get some slide bite if your thumb is just at the bottom of the slide, I suppose it would depend on the ergos of the particular handgun as to how completely the slide's travel is blocked,

awesome, and super-awesome!
Thanks very much for the examples. This is very helpful! (noting the blowback/short recoil correction). So then, would the Beretta 92 fall into the "Browning Hi-Power" catagory to your line of thinking?

My categories are 1. Guns I have and 2. Guns I want.

If I'm not mistaken the 92 is designed after the Walther p38. About the only thing it really has in common with the Hi-Power is the double stack magazines and 9x19 chambering, it doesn't use the browning tilt-barrel design like the P226, Glock, etc. So, same philosophy, accomplished by different engineering, sorta like the AK47 and STG44.
Ha!
...no...just relentless in pursuit of trying to get some things straight in my mind. Being new to semi-auto handguns, it is obvious there are a number of different actions, materials, etc. It is also clear that many more experienced folks choose wording that can be kind of unclear to newbies (no criticism intended). For example, "1911" appears to mean different things to different folks. Sometimes folks use the term “1911” to refer to its SA action, sometimes using "1911" to refer to "big clunky metal guns" (their intent, not mine by the way) and then you get manufacturers calling their gun a 1911, which I suppose is a nice compliment to Colt and Mr. Browning but it can be confusing, especially when they take liberties with the original design like offering different calibers, ARGH! The whole Glock, polymer, striker fired, discussion has been enlightening and allowed me to do some other internet research and put all the pieces together into something that makes sense to me. The responses here have been really helpful for me to isolate the subtleties so thanks everyone!
