The short microcompacts tend to.

Beretta 92 is based on Walther p38. I think the cam locked tilted barrel concept is optimal for modern high volume production. Whatever accuracy advantage of fixed barrel design is probably insignificant for typical pistol applications.

One of the unsung champions would be those super rare single action Walther P88. Walther special tip barrel

Ernest Langdon recommends replacing the locking block at 15000 although it ought to last 20000.

That would be the P88 Champion and Competition. Both use the Browning tilting barrel design.

Those guns don't work any differently than the larger versions, the tilt barrel ones just tend to be more noticeable.

It seems that most handgun barrels will tilt up when being racked. I love those that do not tilt up, like CZ P-01 and Beretta 92, etc. They also seem to be more accurate.
Is my observation correct? What are other handguns with barrels not tilting up when being racked?
CZ M&P 82s and CZ 83s. They both have fixed barrels that don’t move or tilt a whit when the slide is “racked” manually.

Has anyone mentioned the Beretta PX4 and the Smith and Wesson M&P 5.7?

Both use a rotary action.

I also had a CZ 52 which used a roller delayed system. The barrel and the breech were locked together until the slide travelled back far enough that a detent allowed the rollers to separate.

The CZ 52 is a locked breech pistol. It’s not just a delay.

You are correct.

But it has countervailing oddities.
Like a decocker on a SAO. That can fail and fire.

It was fun to take apart and look at the mechanism. But ammo was expensive, and the slide cracked pretty quickly even though I was pretty careful never to fire any of the “hot” surplus ammunition.

As I recall, no FTEs or FTFs until that slide cracked - I think right at the ejection port.

Would it fail and fire even with the firing pin block in place. It’s been a long time, but my vague recollection is that people were removing the firing pin block because the trigger pull so heavy with it in place.

The decockers failed on some of those guns and became a second trigger. They did a change on them to fix the problem. As I recall, a 'Z' was stamped somewhere on the gun to indicate the fix had been done.

If I recall correctly (and it is quite possible I do not in this case), the decocker relied on the firing pin safety to prevent a discharge during the decocking operation and the problem was that it wouldn't hold up to that kind of repeated hammering.
