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.
Having put nearly 1000 rounds through my Taurus OSS DS in .45 ACP, I will admit it is the pistol I would trust my life to. I have a 40S&W version which is proving to be just as reliable. The mags make all the difference when running hollow points through the weapons.
