My father is looking to purchase a new firearm. At the moment we have a remington 870 in 12 gauge and a wasr 10. The question being, should he be looking at a pistol to even things out so he has one of each or would it be better to get maybe a .22 for small varmit hunting, or even better yet something along the lines of a 22-250 hunting rifle. He has asked me to gather info and present it to him. The general uses will be plinking and if needed self defence. Thanks to all opinions.
