Just for fun.

[bannockburn]

Colt M1911.

 

[hso]

Lever action

 

[boatme99]

Revolver.
I tend to think of a Ruger Security-Six. Probably because it was my first carry gun back in the early '80s, and still have one handy.

 

[On An Island]

Colt Peacemaker (it's gotta be all those westerns I watched as a kid).

 

[RetiredUSNChief]

Anything on the TV news now called a gun, is a gun.

Including BB guns, Air-Soft guns, & even Glocks.

Thanks for the explosive laugh!

But do you know how frickin' hard it is to clean Dr. Pepper off a laptop monitor and keyboard?

I'm also in the "context" group; what comes to mind depends on who said "gun" and the sentence it was used in. It might even be a verb, like "He will gun him down."

But as a noun, I don't think of Howitzers first. I definitely think of rifles and handguns.

 

[Pizzapinochle]

Probably a revolver of the old west persuasion or a tommy gun in the hands of a swarthy 1940s gangster.

Guns are those scary evil things that want nothing more than to kill everyone including all the children. When I see a gun I scream and run for my life! haha

It depends on what I've been thinking about or researching recently. For me, at the moment, it would be an ar-15 variant... specifically, .458 SOCOM. Tomorrow or next week it might be a .30-06 bolt rifle or 9mm Luger pistol or an AK.

 

[ohioshooter]

I think shotgun cause that was the first gun I ever saw as a kid.

 

[xxjumbojimboxx]

My "Equipment" pops into mind right away!

Because--This is my rifle, this is my gun! This one's for fighting, this one's for fun!

I knew this was coming

 

[PJSprog]

Revolver. Dunno why. Specifically, my 6" 686.

 

[Darkbob]

Honestly, nothing really jumped in my head. Instead all that popped in my mind was more like a question: "What kind of gun?" Like I was looking for more information on what gun you were referring to. I will say, though, that I was assuming that the gun was man portable and not crew served If you had asked "What's the first gun you think of?", I may have had a different answer.

 

[Hardtarget]

As soon as I read it my thought was John Wayne, sitting astride his horse, Colt on his hip and his lever rifle braced against his leg.

Then as I scrolled down...there was HSO, post #27 and on an island, post #29.
They beat me to it!

When you said gun I "saw" a handgun. No make or model or type, just one held in your hand.

If the news said "a man with a gun..." it usually means a handgun.
"A man with a rifle" or "shotgun" would mean that.

Just my take.

 

[Blackbeard]

First image in my head when I read the question was a Beretta 92FS. That might only be because I handled one recently, but that's what popped in.
