solid, no-slip tactical grip...???
What exactly are you going to be doing that requires a tactical grip? What is your definition of a tactical grip and how does it differ from good non-tactical grip?
There are many gloves out there that market themselves as tactical and put materials like Kevlar in the palms to prevent cuts and pricks. I have seen many like that, and not one actually prevented needles or slashes as advertised. Hell, the last pair my friend had wouldn't even prevent cactus needles from penetrating.
If you want something that not only looks cool (the main reason civilians buy "tactical" gear), but also provides some protection, check out assault gloves. A few companies sell these and we are issued them in the Marine Corps.
Here are the Wiley-X versions
Oakley also has a pair that ups the coolness factor by using carbon fiber for the knuckle guards, but it doesn't add any more protection. The Oakley are actually cheaper, at least at base clothing sales.
