and one last thing to add, never join 2 straps together with a shackle. if one strap were to break, the shackle then becomes a projectile. Try your hardest to never use more than one strap at a time, but if you really need the extra length, loop then through each other. the magazine can be substituted with a rolled up towel or whatever that's light. it's purpose is to allow you to get the straps back apart. never loop them together without something in there or they will become permanently joined.
