How strong is that anchor point? I can't find any info on it here.

There’s a reason why you can’t find any info about it. This is NOT a RIGGER’S BELT or HARNESS BELT this a DUTY BELT, RANGE BELT or GEAR BELT. You can pop the stitching by pulling on it with your hands. It doesn’t even have a really cobra buckle otherwise it would have the 25kn rating on the buckle. You could loop the lanyard through the hole and on the belt or thread the belt through the hole and use the loop simply to attach the d ring to keep the lanyard out of the way for larping, costumes, dress up or to look tacticool or high speed. If you tried to put weight behind it you’ll be falling high speed to your death. It’s meant to hold your gloves, keys, flex cuffs, your lighter on the leash but that’s it. Me personally I wouldn’t even trust a real 25kn cobra buckle to hold my weight. They are not rated for horizontal weight bearing only vertical with the buckle perfectly aligned. If you want a solid true belt for repelling to hold your weight or fall protection but don’t want to be stuck wearing a harness all day. Then save your money and your life and get the arcterxy e220 harness h150 riggers belt. The leg straps are detachable so your not stuck wearing a harness all day for the 30 min you actually need it. Hopefully you didn’t try to use the belt for weight bearing activities and are still alive and well

Can u this as duty belt with safirland drop mid thigh drop holster with cuffs and mags ??

The molle loops on the belt are pretty stiff and pretty tight. That said, if your holster's belt attachment points can come off so you can feed it through. Youll be fine. I use this belt as ny "duty belt" when im a range SO and it holds several mag holders and pouches as well as a holster (non safari) quite firmly.

Is this an actual cobra buckle?

No, it’s a knock off, but it does the job. Mine has never come apart. Works the same as the real deal.
