nope there is a mid size. I had all three on the counter and there is a 1/4 " difference (i think) in the barrel length between the full size and mid size
Is the midsize an older model that is not now in production?
Here is a link to the S&W website that I pulled up, and it doesn't show a midsize, and the sku numbers are 6 digits and not 5, as shown in the previous post.
It would be great to find one with 10 round capacity!
M&P45 .45ACP - Smith & Wesson
Sorry, I missed the "0" in the SKUs.They are 109306 (full size) and 109307 (mid size). If you will look carefully at that web page you linked, you'll see that some of the guns have 4 inch barrels and some have 4 1/2 in. That's the difference between the full and the mid size. (look at the photos of the ones with the 4.5 in barrel, and you will see the extra 1/2 inch protruding from the frame).
Both the full and the mid have the same 10 round capacity and the same frame.
