Has anyone tried or seen adapters to better fit holster loops for 1.75" belts to a 1.5" belt?
This could be an adapter that goes on the belt, or a modification to the holster. I'm open to ideas.
I first started thinking about this when I got a Desantis open top holster. The leather is thin (which I like for a concealment holster) and the retension is good. But it moves around too much - especially on the draw.

A similar issue with the older Galco SSS. As I recall the most recent on-line catalog says this is/was available with 1.5" belt loops. Maybe. But this US made one has loops for a 1.75 belts.
Finally a couple of holsters with slot type loops. These tend to work a bit better for belt that is slightly smaller than the slots. But obviously not ideal.

(The belt in all photos is a Hume B109)
With the different types of loops, there's probably different types of solutions. Curious what people of done or seen done.
I've seen Safariland has a barrel bolt with small strap they offer for their slot type belt openings. But that's all I've seen.
Might that idea work on some leather holsters? Does it actually work well?
