I'm glad the pictures came out well.
Everything about the holster was custom made to my specs. The first holster (for the SD) had the single stitching and larger initials. When I saw how nice the double stitching looked on the P345 holster I requested it for my EDC holster and any others I might order. He had to order smaller letters for the initials, but did so at no extra charge.
There is no relevance to the pistol design. The double stitching is mainly cosmetic, but will enhance strength, too.
This guy (Andrew) is very patient and interested in making exactly what the customer wants. You can detail and customize anything you can imagine!
