Bicycle tube grip.

They work well for someone who doesn't necessarily want to change their grip size, and is happy with the status quo. I prefer Talon grip tape on some firearms, and on my MK, I use the Pachmayr grip sleeve. They move around on some firearms, but work very well with very little movement on my MK. I also like the fact that they fatten up the grip a bit, and absorb recoil shock very well. I'm glad there are many choices out there. They don't all work on different models. Like I mentioned, Pachmayr's for the Kahr, Grip/Limb saver for my HK, and Talon's for my M&P. Switch them around and they don't work for me.

Agree berettabone...I use Talons on my XDs, and a Hogue Handall Jr. on my Kahr.
I do have talons on the Kahr, but as you said, the Hogue (or Pachmayr) help absorb the recoil on the small 9. As you mentioned, It twists a little, but Im shooting a box a time at the range. If I were to shoot only a mag or two there would be no twist at all.

Also, I notice Hogue came out with an interesting beavertail grip....

I just bought a roll of tennis racket grip tape. I can make it as thin or thick as I like! This works well for me...And one size fits all

I use a Limbsaver on my HK.........................................

1" road tube for my Kahrs. Tight fit and super thin. Even stretched one over my XD double stack.

Yeee. 1" tube! I have trouble imagining squeezing the grip into that!
