The Talon Grips are great, and if you're not very handy or just plain lazy I'd say order yourself some.
Now, that said, to be perfectly honest their real innovation isn't really rocket-science and is really just a two-fold improvement on what was already available as the "decal grip" sets that have been around for a while: one, they're cut in a template that allows even the most un-artistically inclined among us to get a decent 360 degree wrap of the Glock lower rather than just settling for covering the grip panels and a few other spots with small strips, and two, rather than using the less grippy, larger/coarser grit grip tape like what was already commonly available in the "decal grip" sets and like what you'd find at the local hardware store as anti-slip/stair tape they utilize a much grippier, finer grit grip tape that is also thinner than the other stuff.
Thing is, as any skateboarder will tell you, it's the exact same thing as Jessup brand griptape which is pretty much the "industry standard" griptape in the skateboard world and found at just about any decent skateboard shop for about $5-$6 a 34"x9" sheet (enough to make Talon-style grips for your game-gun, your carry-gun, and your BUG, with enough griptape left over to make one grip each for about 5 more of your buddies' guns). Plus you'll have enough materials to cut out pieces for the critical support-hand thumb rest area and the surfaces above the grip-panel but below the slide which is really helpful for shooting one-handed.
If you know how to work a razor-blade and/or a pair of scissors you're in business. Support a local skateshop in your town and check it out...
