Well, I think we can do that here too, except there’s really nowhere to go shooting near where I am stationed. Once I get back to Texas, there should be a better availability of shooting places.
Or this 
Shotgun - Don’t have one. I am thinking about getting an 870 or 500 as mentioned above, depending on what extras I could get and price. This would be a bit in the future.
Revolver - Smith & Wesson Model 10-7 is all I have right now. A Nagant is in the mail so I would have to see how that works, although I am in no hurry to buy the overpriced ammo (although I understand it can shoot several calibers). The 6" barrel on the S&W is a bit much for a .38 but it’s quality and a common caliber.
Semiauto - Hard to say. My Sig based on value, although I think the CZ vz. 82 is the most versatile so maybe I’d go that way.
Rimfire - This category is a shortcoming I hope to fix in the future. 10/22 probably.
Centerfire - Ooh. I have the most fun with the SKS, M59/66. I like it because I can actually hit the center of the target with it. I’d miss the Mosins but they take more tinkering and need more urgent cleaning.
God, but I am good. Who da man?
MsRobyn. Sure, she lets you take credit for some of it, but I think we all know who’s really answering these questions. 
Oh, believe me. Everything I know about guns would fit on the front side of a business card. I know how to shoot one, and even that’s kind of dicey.
Robin
Ha. What Robin knows about guns could be written in foot-high letters on the head of a pin.
Shotguns: As far as these go, my new Remington 11-87 isn’t going anywhere!
Revolver: Out of the three I have, I’ll take the largest caliber, my .44 S&W model 29.
Semi-auto: Even though I have a Beretta, my S&W 39-2 is much more accurate, and even though it won’t fire without a magazine, I’ll keep it around.
Centerfire Rifle: Seeing as I only have the one, the .30-06 Remington 03 A3 will stay on the wall.
Rimfire: I guess my Marlin .22 is the best candidate in this category.
I was sorta hoping the noise it makes would be enough to scare off a burglar.
Except that the noise would probably be me, screaming “Where’s the gun? What are the bullets doing in the dresser? How do I load this damn thing?”
You’d better hope that works, because even if you do manage to get it to make enough noise to get somebody’s attention, your chances of getting off a second shot with any gun made in the Ring of Fire come out to no better than 50/50. There’s a reason that those guns go for less than $100. Good thing it’s heavy, at least you have something to throw at them when it breaks after the first shot.
Hah. You might enjoy the writings of the Mall Ninja.
Shotgun: Remington 1100 12 gauge. It’s just so pretty that I could never give it up. It was also a Christmas present from my father in law 22 years ago right after I married his daughter. (We’re still together)
Centerfire: SKS. I have a ton of ammo for it and it’s just so darn fun to shoot. It was also a Christmas present from my father in law.
Semi-auto: S&W 5904 9mm. Another present from my father in law. In case you haven’t figured it out by now, I have a great FIL.
Revolver: Don’t own one. If I bought one on looks, I’d probably get a Colt Python. If I wanted quality and affordability, I’d get a S&W Model 19.
Rimfire: All I have is a Marlin 22. I used to have a 10/22 and would love to have one again.
If I had to follow the rules above, I’d keep:
Shotgun - Mossberg 500 (see above for reasons). I’d get rid of my short barrel Smith 916 12ga.
Handgun - Don’t have one, but want something in .40
Rimfire - I only have a 10/22. No need for another.
Centerfire - Savage bolt action .30-30 (I don’t know the model, can’t find any markings on it). I’d have to get rid of the Winchester Mod 94 Trapper, short barrel, youth stock (wife’s gun), as the Savage can shoot far better than any other gun I’ve used.
I’d like more guns, but what I have serves the purposes I need, and it’s tough to get anything new past the accountant.
Shotgun - Remington 870
Revolver - One of Ex-Tank’s Vaqueros. Hey, at least it’s going to a good home. 
Failing that, the Ruger .357 Blackhawk.
Semiauto - HK USP .45
Rimfire - The good ol’ 10/22 I’ve had since I was a lad.
Centerfire- Ruger M77 in .30-06.
No fair! I have between 30 and 40 guns, and some of them are collectables! 
:mad:
Revolver: Possibly my 1917 Webley Mk.VI, though the others of the same era (two S&W Hand Ejector Sencond Models) would get jealous.
Pistol: Tough one. The C96 Mauser (c.1917) and the Colt Government Model (c.1917 civilian s/n) are a couple of collectables. But I think I’d keep the Beretta 92FS with the Made In Italy stamp.
CF rifle: I’d have to go with my 1979 Colt AR-15 Sporter.
Rimfire: Stainless steel Ruger 10/22 Deluxe with the 22" barrel.
Shotgun: Haven’t got one.
I don’t own guns from all of the categories in the OP, so I’m going to include guns currently on my wish list:
Semiauto handgun: I think the Glock 19 is one of the best all-around handguns–small enough to carry, large enough to shoot comfortably, holds 16 rounds of a sufficiently powerful common cartridge (9x19).
Revolver: Ruger GP-100 (my only revolver right now is a S&W 642)
Shotgun: 12 gauge Remington 870 (the next gun I’ll be buying).
Centerfire rifle: of the rifles I own now I would keep the Bushmaster AR-15, but if it was going to be one centerfire rifle forever I would want a Marlin 336. .30-30 is one of the best all-around rifle rounds IMO–decent for defense, and capable of taking most any game in the lower 48 states.
Rimfire rifle: CZ 452 (bolt action for reliability over the semiauto Marlin 60)
Semi-auto: SAR-1. Takes a licking and keeps on shooting. With 30 round mags and a 75-round drum.
Centerfire: Ruger M77, scoped, bipod, 7.62x39 (kinda rare)
Pistol: Glock 17, night sights
I can’t speak to the rest, but I have a Belgian-made 20 gauge over/under shotgun imported by Charles Daly from around 1920 that I would keep. It was my great-grandfather’s, it is light, & it has the sweetest action of any bird gun I’ve shot. I can carry it for hours without it feeling the least bit heavy. It looks remarkably like this, but with a pistol-grip and more scroll work.
Either that, or I’d keep the Remington 870 12 gauge. Conceivably, I can hunt any bird with it, and still use it to paddle my boat home should the motor die.
Shotgun - Saiga-12 - I can’t help but giggle when holding the loaded magazines. There’s just something both fun and funny about giant detachable magazines filled with 12-gauge shells. Also, it’ll give me my AK fix since my centerfire choice will be used for something else.
Revolver - Colt Single Action Army (antique) - It may not be in any condition to fire, but it’s just too damn cool to give up. It’s got an especially low serial number, though I haven’t gotten it authenticated. (pic)
Semiauto - Sig P229 in 9mm - First gun I picked out on my own. Always a joy to shoot. Also serves as my CCW when I carry.
Rimfire - No real preference here. I haven’t checked out what I have. I got a bunch of firearms from a relative, and I haven’t gotten to the rifles, yet.
Centerfire - M1 Garand - This is a no-brainer. The Garand is just too great of a rifle. Recoil’s not that bad (despite the power of .30-06). It’s easy to load (especially since I’ve got a lot of pre-loaded clips lying around). It’s fun to shoot. TING
shotgun: Simple break action 20 gauge. Light weight, easy to use, and very acurate.
Revolver: Don’t own any
Semi-auto: Have to hang onto the CZ-52. Everyone needs a hand cannon.
rim-fire: Marlin Bolt action .22
Centerfire: SVT-40. nice semi-auto in 7.62x54R As accurate as the shooter. And fun.
