Why don’t Ron’s Dad bring muggle weapons into the fight?

There are many wrong things in this post, but one shines: Arthur Weasley isn't a Muggle expert.

This is probably been discussed on this before, but I’ve actually been really wondering this. Ron’s dad is supposed to be the non-magical expert of the group.

Mr Weasley isn't a Muggle expert and he doesn't know how to use Muggle weapons.

Most muggles don't know and don't want to know how to use Muggle weapons.

In his study of Muggles, he would’ve definitely picked up on the Muggles love for firearms and explosives.

??? Are you American? In the majority of the world people don't have easy access to that kind of weapons. Where I live most people don't love firearms, and I'm considered kind of weird because I would like to learn to use a gun.

Harry Potter and Hermione both grew up and Muggle families. They should’ve thought about this too.

They are from England not from Texas.

"Hello yes I would like to buy a gun to shoot a wizard who has been haunting our world for a long time, just to support my son's best friend."

Dude didn't even know the "usage" of rubber ducks.

This isn't a plot hole, OP.

Arthur isn't an expert. He's just interested in muggle conteaptions is all.

They lived in the UK, where was Arthur supposed to get firearms and explosives?

Tommy guns for everyone! Pass them around!

Arthur has a fascination with Muggles, he's not an expert though.

Muggle weapons can be countered. Expelliarmus could easily work on a gun, a shield charm can work on a bullet, and in any case Muggle injuries don't seem to hurt wizards as much.

There's a lot of reasonable answers like "he didn't know much about them" or "he didn't have access to them". I think those are stretches since magic makes it pretty easy to locate and obtain guns. Its also pretty easy to get instruction about guns from sellers.

I think the most realistic answer is that JKR didn't have much of a plan for how to incorporate muggle and wizard technologies. Other than this vague "magic makes muggle stuff stop working" that gives her carte blanche to ignore muggle tech, she never knew how she would handle someone bringing a gun to a fight.

JKR is not tolkien. She didn't spend a decade creating the world of harry potter before writing the story to make sure the lore was perfect. She kind of ad libbed it and ignored aspects that she knew were going to be difficult to address.

Americans watching Harry Potter:

Molly wouldn't approve of Arthur running around with a gun and Muggle explosives. Or God forbid, Fred and George.

… this is not a plot hole.

Ron's dad during the battle of Hogwarts.

Somewhat related I would have loved to hear more about Harry & Hermoine's culture shocks going from the Muggle to Wizarding world in Book 1. Like having to use a quill instead of pens, electric lights or flashlights instead of candles, etc.

According to the same logic: Tom Marvolo Riddle spent the first 10 years of his life, and every summer until he was 17, in muggle orphanage. He should've learned about guns and explosives. Why isn't he using this in his quest for ultimate rule?

Even if they had guns, I think dark magic would be more than enough to divert a bullet or turn the gun into something useless. At the very least they could just use a shield charm.

I mean did you not watch the duel between Voldy and Dumby in the movie? That was some powerful magic they were conjuring. Don’t see how a gun would be a match against any death eater.

No to just about everything here.

1. Arthur loves muggles, but isn't remotely an expert. He can't even pronounce "electricity", and doesn't understand that a rubber duck doesn't have a function.
2. Arthur has no firearms, and even if he did, he almost certainly wouldn't know how to use them.
3. A bullet wouldn't kill Voldemort or even destroy his body, and thus wouldn't return him to spirit form. A sufficiently powerful explosive would probably do the trick, or a shotgun blast to the noggin, but good luck pulling that off- remember, it's fuckin' Voldemort.
4. The series takes place in England and Scotland, where firearms and explosives are heavily regulated. It'd be more difficult than it's worth to get their hands on them when the magic they've been studying for the last seven years of their lives would be much more reliable.

The guns might not work due to the magic in the air, and protego or a simple spell could prolly block it.

Off topic, but I remember a fanfic where Harry killed Nagini with driving her over with a Tank

If you have good reflexes and are a skilled wizard, you may be able to deflect a bullet, slow it down, or transfigure it. or reducto the damn gun. Plus arthur didn't know the function of a rubber duck, he definitely won't know about muggle weapons.

glock 17 with binary trigger
i see ur point here

It's not American, guns aren't readily available

/s

Because it isn't as easy in the UK to buy guns, and also wtf.

I have often thought about this. Get a 50 cal or two, set them up in front of the bridge, enchant the ammo box with an infinite charm of whatever, and let the death eaters get through the crossfire.

Have you ever read “Harry Potter with a 1911”?

While Arthur Weasley is a muggle enthusiast you wouldn't want him anywhere near muggle weaponry.

People often bring up the “why don’t they use guns???” point, usually but not always Americans.  This misses out several important things: 

 1. Wizards, even Arthur Weasley, don’t know much about muggle technology. He can’t even light a fire with matches without Harry and Hermione helping. 

 2. Wizards by inclination regard muggle technology as at most a crude, inferior and faintly comical alternative to magic, certainly not something that could be used against Voldemort.   

 3. Even muggle-raised students, like Harry and Hermione, seem to “go native” pretty quickly and get used to using magic for things and assuming magic is best.  

 4. Most importantly everyone forgets that the existence of magic changes everything: it doesn’t have to play by the usual rules for our world. In particular I’m sure dark wizards have encountered guns, explosives, muggle weapons etc. at some point and developed countermeasures.

In all likelihood if you tried to shoot Voldemort with a gun the bullets would either just halt in mid air or there would be a sad “click” as his magic stops the gunpowder from going off before he apparates behind you and introduces you to Avada Kedavra.
