I've been around Glocks in one way or another my entire adult working life.
We carried Glock 22 .40's when I was a nuke plant guard, the magazine stayed loaded 99% of the time , except range qual day and the mag were kept loaded for years. They always worked , I never saw a bad Glock mag. They were only cleaned once per year too. I always shot a Perfect score, they are just so easy to shoot well with , for me anyway. We got a small bonus for shooting Expert and I always, every year, got it.
The Iraqi police carried Glock 19's that NATO bought for them, and they pretty much did 0 cleaning with them. They would turn them in at the Gate of our FOB when they went in and they were caked with brown , dried dust. And they still worked when they used them to shoot feral dogs. That sold me on Glock
I own a few, and a 26 is on my "needs" list. I would have had one already but I bought the 42 instead. A 26 is just a solid, no frills self-protection gun that I can trust my families life to and not be outgunned by a methhead with a Hi Point.
They're the most common handgun on Earth probably, everyone uses them. There will never not be parts or service available for a Glock as long as we are a free nation where you can still buy them. And you can just go into any gun shop and buy one. I don't even particularly "like" them but they are reliable and it's honestly smart to own at least something like a Glock 17 because you know you can grab it and it will work. I didn't clean my 42 for over 3 years, including the 1 it sat locked in my car's console and I just recently took it and fired it. No problems.
