so, im holding onto my buddies sks for him, its locked in a case in side my locked gun case. i dont use or touch it or even look at it, im holding it for him cause he lives in the dorm. he also wants to borrow my 12 gauge when he goes to the lake house this week-end, on account of bears and being out there alone i have no problem holding his rifle, or lending out my shotgun for the weekend, but my dad brought up an interesting point should i get him (and vice-versa) to sign off a waiver so to speak in regards to gun custody? all the paper work is in his name for his sks for example, should he sign something that entitles me to hold it for a specified period of time? or does it not really matter to much?
