Bit of a slow weekend so I decided to do the griptape 'mod' on some of my pmags. Tried looking for any sort of template before I got started, but couldn't find anything so I decided to go ahead and make one in the process.
Mind you, this involved 1 sheet of plain white paper, a ball-point pen and about 15 minutes of my time. Isn't perfect by any means, but a rather nice (IMO) template to go off of if you plan on doing this by hand. Print it out, cut out the squares with a razor/x-acto and trace the template onto the back of a sheet of griptape. This template covers the 3 squares on both sides and also the front of the mag... still working on one for the back spine of the mag (will most likely have to be 2 pieces as 1 will bubble up on the bends).
Let me know how you guys like it.
