Does the .45 Shield require a different holster than the 9mm and .40?
It is a little bigger but most holsters are just listed for the S&W Shield with no distinction.

Disregard...I finally got my search to work and don't need to beat this one any more.

The .45 is close enough to the .40 that most holsters fit. If that doesn't work, try one that fits a 3-4 inch 1911. It was weird but a guy gave me his because he got rid of his .45 and it fits like a glove. Other than that, have one made by one of the guys on here.
