Hey guys, I was just wondering, because I am not sure, is the M&P fs .40 built on a .40 frame or 9mm?
The M&P project was built around the .40 S&W.
We were told the order of development & release for the M&P pistols was: .40 S&W, 9mm, .357SIG & .45 ACP.
It was said the order of development followed what they felt was the potential order of use/interest among their potential LE/Gov market, as well as the .45 model requiring some additional development due to the then-anticipated (and later suspended) military pistol trials.
The compacts followed as they could be fit into production.
I didn't address the idea of a ".40 frame", just that they designed the M&P with the .40's characteristics and operating requirements in mind from the beginning.
They designed a frame large enough to qualify as "duty/service" size, since that was their original goal (hence bringing back the honored Military & Police model line name), for the common defense calibers seen in much of the LE/Gov field (which can fit within the same grip frame dimensions).
They designed the frame, including its integral steel sub-chassis, to be capable of sustained use when chambered in the harder recoiling .40 (and .357). They didn't start with an existing 9mm frame and upgrade it at some later point to work with .40/.357.
Granted, the M&P 45 frame requires somewhat larger dimensions than the "standard" 9/40/357 models, due to the dimensions of the .45 ACP cartridge, and I suppose it would be practical to refer to it as the "large" frame M&P ... even though it comes in 3 model variations denoted by terms like full-size, mid-size & compact (using only 2 slides and 2 frames).
It's sometimes a bit puzzling when it comes to how the many gun makers freely use terms like standard, full-size, compact, sub-compact, slimline, etc, or try to figure out how they arrived at those terms for some of their models.
Sometimes it can seem a bit arbitrary, you know?![]()
Fastbolt, I don't know how you interpreted the question correctly but you nailed it.
