They are the grips for the Czechmate, from shop.cz-usa.com
I'm a lefty, and needed more traction for my support hand, so I wrapped the right grip panel with Jessup Grip Tape.
Here's a nifty tip:
Cut a panel that's roughly the size of the grip panel. Make sure it's bigger than the grip panel.
Heat that piece with a blowdryer for 3-4 minutes, then peel the backing sheet off.
Carefully drape it over your grip, paying attention to avoid bubbles or wrinkles.
With lots of pressure, press the griptape hard onto the grip panel, working the adhesive on, all around, until the griptape has formed around the curves and angles. The heat allows the grip tape to be more pliable, and also activates the adhesive so it won't peel or move around.
Lastly, trim the edges off with a sharp blade, et voila!
One other tip Sergio, I use Talon grip tape for my Glock, but the priniciple is the same. . . . before applying the tape, wipe the panel down with alcohol first to remove all traces of oil from your fingers, etc. Once dried, it will stay on better.
