Everyone knows that one of the easiest things for writers to get wrong is firearms.
No, it just appears like that because most writers get flustered and get it wrong, and are then exposed by the many experts. Then everyone assumes that writers getting firearms wrong is an immutable condition, an incurable disease. It isn’t so at all.
The truth is far simpler.
One of the easiest things for writers to get right is firearms. Just ask an expert. My fave expert is another novelist, R. Doug Wicker. He’s even written a three-part article to save other writers from researching the wrong things.
“Firearms for Formulators of Fiction” by R. Doug Wicker:
Firearms for Formulators of Fiction — Revolvers
Firearms for Formulators of Fiction — Semiautomatics Part 1
Firearms for Formulators of Fiction — Semiautomatics Part 2
If you need more than that, Doug says, “If anyone wants advice or help with firearms for one of their stories I’m always more than happy to help. Just ask.”
