not yet 21, living in CA. Looking at a Ruger 10/22 takedown model, this would be a decent first gun, right guys?

also, do any of you know of any other good takedown guns? preferably something that can fit into a pack for future use camping and trail backpacking.

A takedown lever action would be nice but I see them at very high prices whereas I can get a new 10/22 takedown for under $400 or even less used.
