I have a Desantis belt slide leather holster that I purchased for my M&P Shield, I've since traded it for a Springfield XD-S.
After reading a few posts about people saying their XD-S fit their Shield holster I thought I'd give it a try, and it fits nice and snug. Of course I can't see through it to determine exact fit, it does seem to work out nicely from what I can tell.
That said, I'm a lefty and have been trying to sell the holster for a few weeks now without a single nibble, I may as well use it if possible - just wanted to get a general consensus from the board if you will.
Also, I have a Kydex holster that was made for my Shield and the XD-S will not fit, it only fits the leather one.
Thanks for any and all input.
