Having sold a lot of Glocks when I worked in gun shops I never had anyone come back and say the gun didn't work. I like 1911's and have a few. I have 2 Glocks and 2 Glock clones I built. Kinda like 98Z if I knew when I walked out the door I was going to have to employ a handgun I would take one of the Glocks.
The only malfunctions I have experienced were ammo related with my Glocks. They go boom every time if fed quality ammo.
Shoot what you want.
Almost any semiautomatic handgun will jam if not gripped properly.
There are always revolvers for the grip challenged.
