Hi I need a little help. What is the actual difference between a J C Higgins model 30 and 31. I know that the 31 is for .22 short, .22, and .22 Long Rifle and the 30 is Long Rifle only but why. they look identical and it looks like I could take the trigger group out of my 30 and put it in my 31 that always has feeding problems but I don't want to break my model 30.
Any help would be appreciated.
