Black widow - Bianchi 5 Widow Holster

I love the black widow holsters, I use one as my EDC Glock 19. Wanted one for my Sig 226 which it clearly states it fits on the package anyway, unfortunately it would not properly fit either of my 226 pistols. No idea what the issue was except possibly Bianchi put the wrong holster in the package?? Returned without problem.
