Hi LenS....
You are right that the difference in the M&P 45 are enough to need a different holster from those designed around the 9/40. This being said though there are TWO current slide lengths of .45s in the S&W M&P lineup....a 4.0 inch and the 4.5inch model. The only models available to holster makers that I am aware of is the longer model...and this is what I have in stock. I would be happy to create one that is shorter if that is the model you own.
Thank you for the kind words, and although I am somewhat biased, you cannot go wrong with my leather and prices. Let me know if I can answer any questions. If you PM me your number I will be happy to contact you at your convenience.
Take care....oh, and here for your pleasure are a couple photos of detail molding around another M&P, though this one is a 9mm:
