I have a number of choices I could bring besides a number of pocket pistols that would be easy to transport in luggage and carry. Weight and compactness is a consideration.
Let's play a game. if it was you, which would you chose as your one camp gun?
Here they are in no particular order...
-44 mag Redhawk 7.5" bbl (I reload.) Big for a pistol but could be kept loaded in the RV and carried while walking around in the woods. Always wished it had a shorter barrel though. maybe an excuse to cut it down. (edited to add...it will have a 5" bbl soon).
-Mossberg 500 or Rem 870 12ga. with the 18" bbl and folding stock it is fairly compact. (though I don't like folding stocks). The 500 has a lightweight plastic youth stock on it now. I would remove the barrel for transport.
-H&R single shot 12 ga. 18" bbl Pretty light and compact when taken apart, though only one shot and brutal to shoot with slugs. (not a big problem for me, for my wife maybe)
-AR 15 pistol in .300 blackout.- The 11.5" upper is actually my son's but I could put it on my AR pistol. Decent ballistics for a .30 cal from a pistol. It can be taken apart. Can be carried as a pistol.
-Ruger SR 7.62 16" bbl (piston AR in 308) This was one of my Ruger prizes. Can be taken down for transport. Kind of heavy though.
-Saiga 308. 16"bbl with folding stock makes it pretty compact though it is heavy. Pretty darn accurate though.
-Marlin 336 lever in .35 Rem. Pretty good thumper with heavy bullets. I cut the barrel down to 16" bbl and shortened the stock a bit so is fairly compact. It is my brush gun here in Michigan. I could take the stock off to transport.
I don't have any 10mms though.

I have bolt guns and other stuff but I thought those would be the most appropriate.
