what fails first on a stock 1322

There is not a lot to go wrong with a 1322 if you don't abuse it. Maybe down the line, the pump cup may need to be replaced, but I would not worry much about the parts. Besides, if any part needs replacing, a quick phone call to Crosman will have the required part on it's way to you very quickly.

Just shoot it, enjoy it and have fun. The 13xx series of guns seen to last forever if properly cared for.
 
Thanks guys I couldn't really find any answer on google for that I guess no one has a lot of problems with them. This is my first airgun I've always had guns but never an airgun I feel like I've been missing out for along time all I do is walk outside and I'm at the range it's awesome. Any advice you all can give me is very much appreciated.Btw what about barrel cleaning and or oiling its started squeaking when I pump it I put a few drops of pellgunoil and it stopped is that pretty much all the maint on it?
