You have only one choice.

Scoped .22 bolt rifle.

Ruger 4 in. stainless Security Six and some extra springs just in case. The rest of the gun will never break or wear out.

There's a better tool for a number of situations, but the closest to a gun that can do anything that I own is my Steyr Scout.

I choose your CZ 75 SP01! Now what are you going to pick?

JK my CZ 75B will do just fine!

My first handgun bought when I was 19...

My CZ75B

Wait a minute... Aren't Mystical Genies supposed to give you stuff, not take it away?!?

I'd opt for one I want but do not have at the moment, a Perazzi in 12 gauge

I choke out that mystical genie until he gives me my stuff back

I think I would also choose the CZ 75 SP-01 Tactical. The 3rd Gen Glock 19 is a close second.

Sounds like a "gun control genie". How can you trust that your choice of gun won't just vanish.

I don't like this scenario! lol

No, I'm not paranoid.

How about Noveske lower and 4 of my uppers in different calibers? Cheating?

J frame Smith is the only logical answer, but it's a rediculous question.

Remington 870 HD

To the magic genie:
No problem. But I'm kinda busy right now, so I'll have to get back to you on that. Can you come back next week? And bring a list of guns I get to choose from.

Oh, you want ME to tell YOU what guns I have? Yeah, no problem. I'll have to round them all up. Just come back on Monday.

Sorry, I gotta run. I'm going on a fishing trip. I am also dropping some gifts off to some friends.

Depends on what else is going on. If a mystical genie shows up, I'm guessing zombies are soon to follow, so I'll go with my suppressed AR-15 in 5.56.

Reason being, 5.56 is in abundance, while subsonic 6.8 and 300BLK aren't easy to come by.

Simple. Colt 6920.

One gun is very tough. My choice is the Smith & Wesson 686P .357 Magnum with the 2.5 " barrel. A versatile piece that can fairly easily be concealed,good in the woods, and great for car carry. 7 rounds with a back up 6 rounds in a Bianchi wallet holder.

I've had mine since 1998 and will never let it go.

My Mosin Nagant M91/30 with bayonet and sling, and about 3000 rounds of ammo that I have stored up for it.

A rifle makes a great primary firearm thus, my Colt 6920.

I'd have to go with a mossberg 500 with 18.5 cyl. bore barrel, 28" vent rib with removable chokes, and a rifled slug barrel. Good for everything except cc.

My Remington 870 with a couple barrels.

You can't get much more versatile than a shotgun with an 18.5 cyl bore and a 28" barrel with screw in chokes. Add a rifled slug barrel to that, and you're good to go.

Of all of mine I think my trp operator would be the one that would have to stay. I waited for ever for it and its my favorite to shoot

Easy.

The one the Government says is legal for me to keep.

(Not the answer you are looking for but I always will own more one than one legal firearm).
