They state 1320fps....... which probably comes from a 5" or longer barrel
maybe even a Lab barrel?

The Federal 115 +P+ load was also a fast load, per their data but in a lot of weapons
it did not come up with the top numbers in fps.

Only way to know what your weapon gets is to test some out.

Most pistols with a 4" barrel do well with "Standard" 9mm ammo for SD use
with the +P ammo needed in the shorter 3" pistols for maximum energy.
