Yes
But not that much more..... don't walk into it afraid your gonna get bit, because if you have a proper grip, you won't be.
Probably what will rattle new shooters most is the muzzle flash out of shorter barrels.
My recommendation, and it has been proven in real life shootings since time began. Practice with light low/medium recoil loads. then for carry, stuff the +P loads in it...
Under stress, you will revert to your training. you will shoot, like you train. Personal experience tells me that you will actually remember little about an actual shooting.
When the "You Gonna Die Lights" go off. (pilot slang) Slow time sets in, more than likely you will not hear the gun go off, you will not feel the gun go off, You more than likely will not remember how many shots you fired. You will just react to the threat in the manner that you train. May not even consciously remember telling yourself to shoot! This is why a PROPER firm grip and weapon presentation/alignment is important all the time.
Just shoot enough of the +p to know (mental comfort level) if you are going to be able to hang on to it and reacquire your target.
