With the "walls" of the slide and barrel itself being thinner on the 43x and 48 (compared to the 19, 17 and other Glocks), does anyone question the durability of these two pistols?

The G43/G43X/G48 barrel wall is 0.077-inch thick. In comparison, the M1911A1 barrel wall is 0.065-inch thick (16 percent less), and everybody knows how delicate and wear-prone the M1911A1 is. :)

Please...find something significant to worry about.

This isn't a good comparison. A 45 ACP is about 21Kpsi where the 9mm is about 35Kpsi.
But I don't think theres anything to worry about.

No, not at all.
I have fired about 43K rounds (of which about 1K rounds are +Ps) through one of my G43s so far. I inspect the slide, barrel and frame when I clean it after each rage session. But I have not detected any crack or otherwise debilitating damage on them - just normal wear marks.

I know for a fact that those small Glocks are every bit as durable and reliable as their bigger cousins.

If global warming, asteroids, and human effects (holocausts, genetic purges, pandemic denial, wars, dirty bombs etc.) don't kill off your genetic line beforehand. Perhaps "they", or "it" will look at the Glock and say: "my grandpa used to think about killing other humans with these things. Wow, what a world that he lived in, huh?".

I wouldn't worry about the metal parts.

Sometimes the plastic doesn't hold up well. A large number of the G1 and early G2 guns have chips in the thin areas around the mag well, and Glock has kept two G2 frames I sent in for parts updates because they were deemed too fragile to return to me (WTF?!?)

So the metal might be around for the GG Grandkids, but the plastic might not.

While I don't have 43k rounds (like GlockyQ) through my G48, I do have between 13k and 14k rounds through it. Just normal wear and not one malfunction. However my two S15 mags have failed to lock-back infrequently. IMHO, it is a heck of a EDC, especially with fifteen rounds. :D

I've got around 5K through my G-43X. Being that I'm a relative newcomer with It, I'm not worried. She is all completely Stock, and has never failed in any way. I carried it as Primary EDC for a good while and ran 50-100 rounds through her every week. I have gone back to carrying my
G-23 more, just because things may start getting bad before long. Never can tell lot of things missing at the Grocery stores.
A Kimberly Clark Plant has 18 Wheelers lined-up at the gate waiting to get in to load up with Toilet Paper. I heard they are Hiring Shotgun Guards. Lol

Yes. I have replaced the following parts 3 times (even though they kept working fine):
  1. DPM recoil spring system that I have been using in lieu of the OEM RSA. The DPM system has proven itself to keep functioning reliably over 8K rounds.
  2. Firing pin sleeve and cups.
  3. Extractor.
  4. Extractor plunger spring.
  5. Firing pin safety and spring.
  6. Slide lock and spring.
  7. Slide stop spring.
I have also replaced the following parts twice:
  1. Extra power mag springs that I use with Pearce+1.
  2. OEM mag followers that I use with Pearce+1.
Finally I have replaced the following parts once:
  1. Trigger Mechanism Housing.
  2. Firing pin spring.
  3. Magazine catch spring.
Other than the trigger spring inside the TMH that had actually broke but kept functioning (See, https://www.glocktalk.com/threads/keep-your-glock-parts-handy.1809392/), other parts have been replaced as part of regular maintenance much like “oil and filter change.”

Wow! Thanks for the report!

Have you contacted Shield Arms to have them send you the +10% springs? May cure the lock-back issue.
I have the 10% springs in both my mags. Still, now and then I will get a failure to lock-back (not a big deal). My G48 is very early silver slide. My "slide stop lever" says part # 47876. The most recent part number is 47877. I suspect this may be part of the problem. I'm trying to get the more recent part #47877 - no luck yet.

I'm around a lot of people that use Glocks for a lot of different applications, carry, duty, competition, etc. From a G42 to G20 and so far I don't anyone that has worn out a Glock factory barrel, personally never seen a crack slide from use but seen a few post on the interwebs. 99.9% of us will not put significant wear on this pistols to cause concern. I been shooting Glocks for over 22 years and other than recoil springs and some miscellaneous parts have never replaced mayor components.
