Thanks for all the comments. As noted, it was mostly curiosity since I have already armed my protagonist. This work will probably disappoint gun-bunnies as the coverage of weapons is rather cursory. Most readers don't care about make and model.
The person in question has been holed up in a relatively well supplied cabin all winter, and has finally emerged with the hope of getting some fresh meat. The character is not a survivalist, weapons expert, combat vet or other type often found in post-collapse scenarios.
Unfortunately, upon returning to his supposedly hidden cabin, he finds it occupied with a number of heavily armed biker types, and in no position to contest the occupation, has to move on, leaving behind most of his gear and several firearms.
I did some random selections using dice and a gun buyers guide. He ended up equipped with a 22 revolver and a 22 hornet single shot with scope (type unspecified). I decided that worked well, as the hornet makes a good small game killer and can take larger critters with a well placed shot, but 50 rounds will still fit in a pocket. The 22 revolver is mentioned only as a 'Smith & Wesson'.
