Query: Grippy on Both Sides!

I got this to put on some of my pistols for range use and I can say that it adheres quite admirably to whatever surface you put it on. I even put some on the bottom of my boots to help give the extra worn areas a bit of extra grip and in three weeks of daily wear the little bits of tape I added are still there. This is also a LOT of grip tape, I could redo everything I've done at least a dozen times. It's more enough to cover an entire household step.Pre-cut panels of grip tape are easily twice the cost for a single firearm; this stuff is enough to do over a dozen guns and the amount of prep time is trivial. I would recommend that anyone who wants to add a little bit of extra grippiness to their competition pistols to look here first. It took maybe five minutes to make a pattern for my pistols using painter's tape.
