Welcome to the forum. I have also heard both arguments about ammo. I usually carry holly points in the medium frame autos like the bersa Thunder. Never had one of the small poly frame .380, but I would probably go with FMJs due to the short barrel. I have had a couple of the tiny .32s in poly frame, KelTec P32s and just got a Taurus TP-732 in .32. Will be using FMJs in that gun. That is just my opinion.
