I thought that it was intersting to see the quality of the metal that is used for the slide. At the :35 second mark it gives you a good view.
Edit
Here is the difference between cheaper and more expensive guns.

After a KaBoom the HK was sent in and all it needed was a new frame to be back in business.
With a HiPoint you spend the rest of your life being called stumpy.
Are you suggesting that the catastrophic failures were essentially the same? The poster from The High Road whose pistol was being discussed in your link
said there was "obviously" some kind of obstruction in the barrel, but he offered no explanation for how it might have gotten there between shooting some OEM ammo and loading up the gun-show ammo. The fact that the barrel on the HK was still useable in the rebuild suggests there was no bulging or evidence of excess pressure in the upper at all, which suggests to me that the poster was mistaken about an obstruction being present. But even if there was an obstruction that moved out through the muzzle when he fired the overloaded cartridge (assuming he's right about that too), causing no damage to any part of the upper, that's hardly comparable to hammering a bolt into the muzzle and then C-clamping it against the opposite end of the slide, turning the weapon into something more analogous to a pipe bomb than a working handgun. No matter how much the quality in materials varied between the two weapons, if the HK had been rigged the same way, it too would've exploded the upper.
As I was typing the above, it occurred to me that some may not have ever seen the longer version of the High-Point video, and may not know how that "experiment" was set up. Take a look, and you'll see what I mean about the materials not making any difference:
That was the last in a series of videos those guys did in which they concocted every manner of torture-test they could come up with in an effort to prove or disprove, as the case may be, that Hi-Points are inherently junk. Turning it into a literal pipe-bomb was the only "test" that caused a catastrophic failure.
I'm not defending Hi-Point. I personally would not own one because of the bulk and weight. But there is very little evidence out there that supports the rather common contention that they're pure junk. I think all the people who own one that have posted in this thread say they're reliable, and the guys in that video seem to agree. They couldn't even make one blow the lower up when they were trying, so I guess they're even more reliable than an HK USP! LOL
