Really? Ever seen a Kel-Tec P32, P3AT, PF9, P11, or P40?
Screws are used by companies too cheap to install captive pins.
Given that Kel-Tec's target market is at the 'economical' end of the spectrum, that's probably not too surprising. And I can't say that I was ever impressed by the number of disposable connectors (like roll pins or rivets), that are used in some expensive and quite popular firearms.
As my friend Captain Obvious once famously observed, "All gun owners have opinions - so what?"

Myself and 4 colleagues of mine teach defensive courses, in which enrollees would depend around 1,700 rounds in a 2 day class. No XD ever made it, budget ARs tended to die, I wasn’t the shotgun trainer but he told us a lot of his students ran KSGs and their screws would fall out of break in ways that would shut down the students’ training if we didn’t keep loaners on hand for this purpose.
MAYBE I could see a screw built .22 being reliable enough, but nothing serious.
What we see works best (I was the head pistol guy when I was doing it) was, Glock, M&P, Baretta M9s, CZs of all kinds (I particularly like the P-07 and was impressed enough with it to by my own) Walthers work pretty good, SIG jar great but I saw the spring die in a SIG P320, but sit mostly rocks
And you’re right about the roll pins. I’ve had to replace quite a few after 2000 ish rounds, but after that I don’t see them walking anymore. My P-07 is a hair over 37k rounds and on its second spring, but that roll pin still looks good to go
By the way, we had one young guy in a class in Florida running, I shit you not, a luger. He dominated with it too. I couldn’t get over the sight picture. Imagining cracking open a book just enough to let a tiny bit of sunlight through, and on the other side, you’re trying to focus on a sewing needle. I was barely on steel at 25 yards with it but he was ringing them like a xylophone. He had a few jams but it didn’t go down. He just racked his toggle and the next round would chamber.
A Luger. In a 2017 defensive class. That’s pretty dope.
