That's strange...I've owned three 5.11 belts (2 black, 1 brown) and have never had that happen. Did you contact 5.11 and see if they'll replace it?
And it's not plastic on the edge, only the middle is reinforced with plastic.
Sounds similar to what I picked up.Standard double horsehide, iirc.
I do not know if Rafters is still in business. I have read some bad complaints from people never receiving their orders. I bought a holster rig probaly about 3-4 years ago no problem. I heard good things about their belts but too many complaints about service.
