I have a VFG on the way that I think I'll actually find usable, and comfortable enough. It's the Mission First Tactical (MFT) REACT Ergonomic Grip (REG). I ordered it from Wing Tactical yesterday, and got an email today saying they shipped it, the Strike Industries shotgun barrel clamp, and some other stuff. Strike Industries didn't have the black shotgun barrel clamp in stock, and probably won't for several weeks, but it was cheaper at Wing Tactical, one of their authorized dealers.

https://missionfirsttactical.com/REG MFT also makes a REACT Quick Detach Grip (RQDG) I might like since it's
even longer, and unlike a few of the grips I've already tried, it's smaller in diameter where your little finger goes than where your bigger fingers go. Instead of big where your little finger is and little where your bigger fingers are. But it's also like a hybrid of a broom handle style, so it may be too narrow. It's also a lot heavier.
Full fist-sized textured vertical grip that quickly detaches or attaches without the use of tools and provides a positive grip surface. Allows the support hand to apply rearward pressure keeping the weapon shouldered, yielding better muzzle control and accuracy.

https://missionfirsttactical.com/RQDG If I had a gun store, I would rig up a stock with a horizontal wheel up front and have a bunch of different VFGs attached, so people could shoulder it and hold each VFG until they found that one Goldilocks grip that felt
just right. You could have 2 dozen small Pic rails screwed to the rim of a plastic bicycle wheel, and have a different VFG hanging from each one.
