I have an afck and I noticed that there was a difference in my afck and the other afck model. mine doesn't have those nuts in the handle like you can see in the picture the screw goes directly into the G10,but the other ones have nuts in the handle. I think mine is the older model. Did BM do this because there were promblems? I've been carrying it only for a few weeks and still no problem but later on is this going to be a problem?
