Bought my M&P 9C the 4th of July weekend. Submitted rebate and it showed up on the Milano site August 27th. Called Milano, they said they approved the rebate and sent it to S&W in the middle of September for shipment. S&W says backorder'd. I'm still waiting, and frustrated.
My perception is that they are about the same size as the large grip. YMMV. I use the MTAC Minotaur holster. The gun fits well with the CTC and the holster is very comfortable at the 3:30 position.
I have an M&P 9C and bought a Comp-Tac Minotaur MTAC Holster yesterday for it. Wore it concealed in the afternoon and last night. Extremely comfortable at 3:30 - 4:00 position. Uncomfortable while driving with the gun in the holster at that position, but the empty holster was not a bother...
My name finally shows up with a valid entry and 8/27 as the entry date. I think I mailed the rebate 8/8. Now we'll see how long it takes for the mags to get here. Hurry up & wait.
I bought the 9mm compact with crimson trace grip factory installed. It's like getting a fourth grip with the gun. You still get the 3 that come with it, but you have to take the CTC grip off to be able to use any of the other ones.
I just bought a Blackhawk paddle/belt holster for mine. I have the 9mm compact with crimson trace as well. I like the easy on, easy off aspect of it and I can wear it in different positions.
Good luck in your search.
