Started this a while ago (this thing broke the vise ), finished it just now. The strap closes finely around my hand and secures that I hold it the same every time. It is build like my Scrapshooter, a Shackle clamped between a flat metal bar and fitted with grip material (in this case some foamy rubber and a red textile strap). I haven't shot it yet and won't shoot it with the red tubes you see. These are just for display. I hope you like it.
