Isn't SAAMI spec for .40S&W the same as standard 9mm, at 35,000PSI...? Which would make it even lower than the 9mm+P's 38,500PSI, for that matter...?
You are correct...the 40 & the 9 have the standard pressure. Now the following is simply my personal speculation, but I believe the .40SW has a faster pressure spike, which is seen in it's snappiness (recoil)... I use to be a "nothing-but-40-guy", but transitioned over to the 9mm two years ago. The newer bullet designs for the 9mm made the .40S&W moot, again, just my opinion...YMMV
