I tried a clip on my shield, not the same one you name here, but similar. Just not my cup of tea. It held ok, but I wasn't crazy about the gun riding along my near bare hip/buttocks. I figure long term that won't be great on the finish. Not that it was a huge consideration. If you use and carry one every day, it will show it sooner or later.

The thing that bugged me the most about it, and had me take the thing off and toss in a drawer, was that it interfered with my getting a good grip on the slide for loading/reloading the weapon.

I reach over the top with my weak hand to operate the slide like shown in the pic. Not to start a debate over this method or slingshot. It's what I trained and what I know.

It got in the way, so I ditched it. YMMV
