Many wartime pictures suggest that the use of small size bombs under the wings was widespread from the P-40F onwards. On the other hand, some references suggest that small bombs were used also by P-40s in the Phlippines campaign (1941) but it's not clear what version carried them as there were both P40B/Cs and P-40Es operating together (source: Bloody Shambles vol. 1 by C. Shores)

Will the new P-40 models have an improved DM?

Yes, they will. At least the 3D, texture and collision boxes are much more detailled.

14th. Air Force P 40s were often armed with the bazooka type rocket launcher, as seen on the P47 in IL2.

I tend to disagree. While Bf109 do have awful texturing (old style), the 3D shape of the P-40 cockpits, especially the canopy frames, is really wrong.
So in summary, P-40 cockpits are wrong, while Bf109 ones are only ugly.

Many people won't notice when something is wrong, for lack of expertise, but they will surely notice when something is ugly :)

That's quotable :) Both could use some tlc but super happy about the P-40 in general!

P-40 cockpit frames are wrong AND ugly.

So, no more one shot knocking out the engine or damaging all control surfaces

Normally, no more. The following parts are separated : engine body (cylinders), radiator, carburator, oil tank, fuel tanks (x3), control cables (x4).
To my opinion, the radiator and wings fuel tanks are the less protected parts.
The other parts are pretty secured and well protected, actually.
