It's nice to see new work as 10mm Shooter makes a fine holster!
I bought one for my Shield about three years ago. I really liked it then and still really like.
I gifted my 9mm Shield to a Marine Corps buddy late last year and was going to include the holster, but at the last moment I thought to check how my 45 Shield fit in it. It took a bit of pushing. but it fit. Then I thought, holsters fit up against your piece just like underwear...a man doesn't gift underwear to another buddy will have to find his own holster.

10mm's holster has broken in just fine for my Shield 45
