Famed gunboard troll "okjoe", whose internet antics I've followed for... oh... more than ten years now, has taken to spamming the in-boxes of gunbloggers, apparently.
Okjoe is sorta the Dr. Nick Riviera of guns, having come up with a plastic gizmo that you glue to the side of your gun to rest your index finger on while you pull the trigger with your traffic digit. He will be happy to sell you this gizmo.
Now he has a new device: The Halo Sight. This is a plastic hair curler that you affix (and I quote) "with a strip of double sided adhesive tape" to the top of your Glock's slide. (You know, the part of the gun that moves back and forth so fast that sometimes the factory front sight will shear off and head for parts unknown...)
I predict that this will become popular with the kind of people who tape ziploc baggies of aquarium gravel to their $500 speaker cables.
