left hand holster mark 3 with red dot

[fast ed]

I am looking for a leather holster that will hold my ruger hunter 6 7/8 barrel with a red dot sight. My problem is I cannot find one in left hand. Any thoughts

 

[22/45 Fan]

In Kydex, not leather, but is ambidextrous and holds any MkII, Mk IIi or 22/45 with a red dot:

I'm a lefty and I have one for my 22/45 Mk II and it's very secure. You will have to reverse or shorten the factory Weaver rail to clear but that's easy.
