Do NOT use S&W M&P compact in Blade-Tech Revolution holster! -- Seriously, the mag falls out in the holster if it is tapped on the side!!
Yes, I know it is for the fullsize, but putting a compact in a fullsize holster is not really that outrageous or even illegal. The holster is still an amazing value!

Most of the time I like having a full size and compact of the same pistol because I can interchange magazines and holsters.
This is not the case with the Blade-Tech Revolution which is for a full size (they do not make a Rev for compacts): http://www.blade-tech.com/Smith-Wesson-Holsters-for-M-P-Series-Pistol-Revolution-Series-Holster-pr-1034.html#product_images
I picked up one of these locally very inexpensively ($30 I think) because I needed a holster to go the range that day. Having both a paddle and belt attachment they are a bargain and pretty comfortable. However, for OWB concealment there are holsters which hold the pistol closer to your body. For CCW I use an IWB.
I decided that I wanted to run to the grocery store and switched out the fullsize for the compact. To my surprise the mag wasn't seated! Hmm...I locked it back in and put on my jacked and must have slapped the side because I heard the mag click out again!
After experimenting briefly it became very obvious that any type of push to the side or handle of my 9c caused the mag release to engage in the holster!
Put the FS back in and no problem. The FS stayed in the holster.
Below are the stock photos from the Blade-Tech website. These prominently display the "M&P" logo, while mine has a big "S&W" instead. Maybe this has been fixed in later versions, but I would try it first. I would still buy another one again.
