"Sword to a gunfight? 'Fraid not, old chap; you've brought a gun to a magic-swordfight. I'll graciously allow you to apologise for the original slight, instead, if you're afraid to die."
"Magic Sword?"
"You've heard me right. I'll have you know that, in addition to being indestructible, one swing can cut mountains! One swing, and anything in it's path will be split in half."
"Damn, that sounds powerful..."
"Correct! Now then, are you going to lay down your weapons or do I have to-"
BANG
"OW! MY LEG!!"
"Yeah, next time grab some enchanted armor with ya too, fam."
"I CURSE YOU AND YOUR FAMILY TO PAIN IMMEASURABLE!"
BANG
"OW, MY OTHER LEG!!"
