It's the difference between the recoil impulse of a 180gr FMJ (assumed) .40 S&W v.s. a 115gr FMJ (assumed). Unless you've shot the two rounds, you won't understand what I am about to say.
9mm recoil impulse = feels like a pop
.40 S&W recoil impulse = feels like a snap
Sometimes, .40 S&W can induce a flinch in unprepared and brand new firearms enthusiasts.

If you were shooting a 9mm Sig Sauer handgun, the difference you are describing is due to the different fire control systems of both pistols. One is a hammer fire DA/SA. The SDVE is a striker fired. Hammer down, the Sig's first trigger pull will be long and heavy. The subsequent shots will be in single action mode, short and crisp. The trigger pull of the SDVE is long because of the type of striker system in it. The SDVE has to fully cock the striker, hence the long trigger press. Other striker fired pistols pre-cock the striker to some degree.
You can modify the SDVE's trigger pull to be lighter, but not shorter. You can also fit an Apex Trigger shoe to eliminate trigger over travel.
