I notice quite a few of the posters who complain about the Beretta mention the .40 caliber Model 96, pick a letter.
When I was experimenting with the .40 Smith and Wesson I chose a Beretta 96 FS Inox as the BEST choice for working with the cartridge.
Better than the Glock,(Too apt to Kaboom if you aren't careful with reloads), and better than the offerings by Smith and Wesson, (Too apt to fall apart with heavy use and heavier loads).
There weren't any H&K USP pistols in my area at the time.
While my testing convinced me to really despise the .40 S&W cartridge, I had absolutely no problems with that Model 96 pistols.
It didn't break anything, didn't blow up and should have, and was reliable with loads that should not have fed.
Faults,,,,,there was one.
I could not find a load that would group to my standards and I can't fault the pistol for that.
I haven't shot a .40 caliber yet that I would call match accurate.
Haven't tried a USP in .40 yet but I might.
As for the P38/P1 breaking locking blocks, yes some guns did do this.
Especially late war pistols that were hasty built using what amounted to slave labor.
P38s had a pretty nasty habit of pitching the top cover too.
Something the big doller pushers of 'collectables' fail to mention very often to prospective buyers
Early aluminum frame P-38/P1s are also know for cracking the frame at the slide release lever slot.
Walther corrected these faults with the later aluminum frame guns with the reenforcing bolt in the frame and in the god awful expensive last run steel frame guns.
