They’re even reliable with Korea made mags in them. I have a Gen 3 Glock 22 which never jams and I put a 9mm barrel and Glock 17 mags in it when I feel like it for range time. Perhaps the key to the Korean mag reliability is that they’re not ‘drop free’ so they fit nice and snug in the mag well for consistent feeds. Seems to be why they work so well in my Kel Tec Sub 2000 models.
Automatic pistols have been around so long that just about any of them from a reliable manufacturer with good mags are extremely reliable.
I personally think the double column mags are more reliable than the older single stack, especially with the 9mm which has a fair amount of taper from base to mouth. This taper makes it feed into the barrel reliably but also makes it not fit mags as well. I have noticed that the double column mags such as Browning Hi-Power, Beretta, Sig, Glock etc. all position the top cartridge more securely than the single column ones such as the Luger, P-38, S&W Model 39 etc.
It is actually getting unusual to find a modern high capacity pistol which does not feed, fire, extract, and eject perfectly.
