Aren't those 88 grainers designed for the 380?
380 is also 9mm as is 9 mak
380 is 9X17
Mak is 9X18
Luger is 9X19
and there are others as well, including 9X21, 9X23, and 356TSW
I used mid table Longshot data and was getting an easy 1400 fps. I worked up to max and was hitting a full 1500 fps.. Good accuracy, no excessive pressure indications what so ever. They're snappy, but not painful to shoot by any standard for 9mm. Those are the loads both my wife and one of my daughter in laws prefer to carry for S.D.. I figure a 90 gr. JHP at 1500 fps should due just fine for a SD load, as long as it's 100% reliable.
