That amazon item is nothing but a cut strip of the stick down 3M "step tape" from the paint department at lowes or home depot! $10 will buy you a lifetime 500 gun supply....
I too like the granulate from those guys, I used to tuck it under the grips like the amazon item but last few years I leave a tiny gap, just be sure to degrease the front strap or it won't stay....
It does everything for me that a $300 dollar front strap checkering job does, except look cool. I am one of those people who really cannot manage a 1911 well without rough tape or checkering....not true for everyone however.
