Safe or secured container for hiking

[johncmng]

What do other people use to store their pistol in a state park. I want to have one but only if I can store it if not for immediate use. Does anyone has a safe or a container that is lightweight and I can have access to it in a relatively fast manner. Light weight is the key work here.
Thanks
