There are two issues that have plagued automatics since their inception 100 years ago.
The first is ammo that isn't suitable for the gun. I was a problem even in the 1900's, during WWI. Ammo makers weren't working carefully with gun makers and the resulting product selection was spotty, at best. The consumer public doesn't like to pay premium pricing for premium ammo, and contributes to the problem buy trying to shoot substandard loads.
Guys, it's not "range" or "practice" ammo if it's cheap, malfunctions, and won't be your carry ammo. Ever. You train with what you will use. Shooting substandard ammo only creates suspicion the gun is unreliable and you can't trust it. If you paid good money for the gun, why do we consistently try to cheap out on the ammo? I get the same thing with car owners, reading codes all day long about misfires, complaints over driveability, yet when questioned they are pumping 85 octane 18% gasahol by actual test in their car. Just to save a few pennies. It's false economy. Better to buy a cheaper gun and use premium ammo if that is what it takes to get reliable and trustworthy function.
The second problem is the consumer public in the first place. As outlined above they are less than experienced about design, use, and operation of weapons. Guns are not their focus in life, it's a hobby for most. Extensive education, training, and research into problems isn't their way of life. Most pick a gun because it has gravitas, a great advertising campaign, and pulls all the right strings to get money to levitate out of their wallet. Add in the social tier construct of status and we get social buyers who either denigrate cheaper guns or who refuse to recognize their expensive favorites are just as prone to malfunction.
It then goes to who has great customer service - which is a fall back position for a lack of knowledge and skill on their part in the first place. If you buy based on how they will support you after the sale it then raises the question is that product your best choice, and secondly, why do you need to have your hand held while you work thru your learning curve to a higher level of understanding?
Social based consumers bristle at all that and demand the gun shoot whatever they shove into the chamber regardless of physics. They are the customer, by Jove, and the customer is always right!
Shooters understand the gun is a dynamically operating machine, and adjust their handling and care to do their best with it.
Sort out who is approaching guns with an attitude that they are no different than any other commercial appliance and you begin to separate the sheep from the goats.
