I wear my VMII quite regularly but this past weekend was a new test for it.
I went 4-wheeler riding for about 4-5 hours with it. My Sig 229 never budged once. This was all over rough, bumpy, twisty terrain on a super heavy 4wd that feels every bump.
I was worried for the first hour or two, but after that, I was happy knowing it was not coming out. My belt was normal snugness, not tight.
Just thought I would share.
