I use a pair that has the regular "suede" palm, but leather around the fingers and along the thumb and pointer finger. They are literally perfect for shooting with an Ultimak because the leather is right where my hand touches the gas tube, and I get no problems going thumb-over-bore. The "suede" palm does good to protect from radiant heat as well, so for shooting an AK with wood handguards, the regular plain jane gloves will work just fine. They have the "tactical" line if you want "tactical" colors as well. I'll probably get some, not for the colors, but to support the fact that they're a mainstream company making a product with "Sport shooters" in mind. I dunno, I just like that.
Problem I just realized, though, is I don't see these on their site... dammit all!
