It would be nice to have some. Of the guns I worked with this year, perhaps 40% either arrived non-functional or partly functional, or failed within fifty rounds. While that’s skewed by the high percentage of prototypes I encounter, enough of the production guns are unusable to make me wonder. I am becoming a big fan of bayonet mounts for rifles and backup pistols.
On the plus side, certain companies consistently make guns that work. I suspect their QC process is organized to work on numerous stages and not just at the test firing before shipping. Conversely, I don’t see how some guns ever made it out of the door — they couldn’t even be loaded, much less fired! With the cost of each transaction in time and money, sending things back and forth isn’t the answer. And breakage during a defensive situation would be even more of a problem.
