I am afraid that your theory just does not hold up to the reality of the 40 S&W. For years I have read that the 9mm operates at about 30,000psi. The 40 S&W depending on the load can approach 50,000psi.
Let us look at the destructive power (on the pistol) from a real life situation. One of the worlds best pistols the Browning High Power had to be almost completely redisigned because it literally started to fall apart when FN first rechambered it for the 40 S&W. A special extra hard frame was developed for the 40 S&W. AS a matter of fact FN never did perfect the High Power for the use of the 40. They had problems with the tremedous pressure actually cracking off one of the rear frame rails. So FN's only solution was to actually saw off this portion of the rail on all the new High Powers since it would have cracked off in use anyway. Very heavy springs had to be substituted for the standard High Power springs which made cocking the hammer or drawing back the slide almost impossible for some women or some older men.
Your statement that the pressure of the two cartridges is almost identical just does not bear any relation to actual real life tests. If the two cartridges had the same pressure FN would not have had to use horrendously more powerful springs in the new High Power and frame rails only came apart in the 40 S&W chambering not in the previous 50 years of 9mm chamberings.
AS far as velocity is concerned there are a lot of loadings out there for the 9mm that far exceed your rather week posting. I have seen some 9mm loads chronograph velocity readings right up to almost 1400 fps. Try that with a 40 and you will probably see it go up like a grenade from the pressure.
If I desire a big cartridge I will stick with the .45acp. But for all round fun, economy , low recoil, high velocity and, much better average accuracy, and longer service life of the pistol I'll stick with the 9mm. I want nothing to do with all the headaches associated with the 40. Just my personal preference. W.R.
