Own multiple - FAB Defense 3 point/2 point/1 Point Tactical Weapon Sling

I own three of these, 2 bought from optics planet, the 1st two were great but the last one is much shorter. Comparing the 3, the first two are actually ensembles different and sewed together at different points than the 3rd. It looks like I could take it apart and put it together the same as the other two, but talk about a hassle and likely not worth the effort.
