Good news - bad news. It seriously clamps down such that you'll probably break a fingernail if that is your only leverage. That does help make the case for it being the single attachment point for a holster in that there will be NO rotation of the pistol/knife when the Ulticlip is used. You might try the back side of a knife blade if you are wearing the pants/belt when taking it off. I found it easier to remove after removing my pants for the day.
I’m thinking for camping, hiking etc. I generally wear nylon camp pants. Most have an integrated belt, so it’s not possible to put on a flashlight in a sheath, or a small sheath knife or multi-tool.
This isn’t really the solution without forming a new Kydex sheath, but it’s worth thinking about,
