Issued weapons are "rode hard and put away wet". These things endure the ultimate test of durability by them being issued to some shitbag G.I. A lesser weapon would never hold up. It sounds as though the problem with your particular weapon could have been in the magazine.

The biggest downfall to the 92FS, is that it's chambered in 9mm. Now there is nothing wrong with a 9mm for concealed carry, range, plinking, etc., however, it's not the round to fight a war with. All of the 92FSs I've shot have been reliable and accurate with a trigger that breaks nicely. With that said, only God may have known the last time it had been cleaned prior to me firing it.
