Hey everyone just like the title says (kind of) im looking for a sling for my
M1A, im not sure which to get, A canvas one or a nylon one. Which on is more durable, comfortable, better, and will be used if SHTF. Any help or advice is greatly appreciated. Thanks =) !

PS: LOOKING FOR A USGI GREEN ONE, I LIKE THE "MILITARY LOOK" ON MY M1A.
