The stitching conundrum is interesting but at the end of the day, it's just a piece of leather and many members here could duplicate it. Another respected gun leather maker has often opined that current wait times are only because manufacturers aren't willing to expand and fill orders in a timely manner. No offense intended to Sparks or anyone else. It's still just leather, thread and dye.
I'd agree with the other poster that the stitching is inconsistent on the subject holster.
I'd like to have it in hand to figure it out.
EDIT: I think most of the stitching is done and then the last bit, from about 6 stitches above the tension screw, up and a few stitches around the corner, are finished by hand.
