I have used .40 for 20 years . I have all the common guns and some not so common. The Glock 22 is my favorite duty sized gun and I carry a 27. The 226, 229, USP, and Beretta 96 are next. My CZ 75 is right up there but did have a few jams early. Shoots great though. The last one I bought was a 320 and its a fine gun too. The Taurus Beretta clones are great guns as well. I know you said no Taurus and for the most part I agree but that model is pretty universally liked.
Another option is buy a Glock 10mm and have a 10 and be able to shoot 40 as well.
As far as the gen 3 Glock having issues, I've read that a lot but every agency including my county used the gen 3 40 at some time. I never saw an issue despite seeing hundreds of thousands of rounds fired. Many of the issues were blamed on a weapon mounted light. At least one of our local departments kept a light mounted. Again I never heard of or personally saw an issue. The only gun I've personally seen fired as much in .40 is the 229.
As others said, you really missed the boat on a good used 40. I bought 226 for 300 and USP for 400. Px4 for 249. Glock 23 and 22 (I didn't get a 23) for 299. And M&P for 199. Sig 320 for 300. Back in the "great 40 turn in". My county switched to a Glock 17. But many many agencies abandoned the 40 for 9mm. Ammo was cheap too. RANGER t was 13 bucks for 50. HsT was 15 or so. Sounds like 30 years ago but was just 2

I might consider getting one of the discontinued models while you can and getting a Glock later, even though the Glock is my favorite. GLOCK still makes a 45 GAP and may be the only company that never stopped making the 10mm......it will be many years before they drop the .40. Lol.
