K40 Letter Designator Question

[targetshooter]

I've been looking for a K40 in my area, with no success. I found one on the internet which has the model number K4043A. I could not find the letter A designator on the Kahr website. I sent an e-mail to the seller but he has not responded. Does anyone know what the letter A designates ?
