So my new 75B's straps are smooth as a baby's... and I want to change it. My Rami, PCR, and Shadow 1 all have at least vertical lines machined in. I have watched some YouTube videos on self checkering, and the matte stainless steel will be easier to "fix" than a polycoat one (which means I will probably do some usual trimming of the trigger guard where my middle finger tucks in. Anybody done this themselves? It is pricey to have a smith do it. I'll still need to find someone to bead blast too.
