I have other carry ammo that I bought here and there, because it was available, but I order Underwood 90 grain XTP, both P and +P from underwood. There really is no such thing as +P 380 as there is no SAMMI spec for it, but Underwood claims it has 100 FPS more muzzle velocity. I have shot the Underwood +P 380 in all my 380's to confirm function. It works in all, no exploded guns.
The Hornady XTP feeds in all my guns with any brand ammo, Underwood, Hornady, Fiocchi maybe others. The 380 90 grain ,in particular, is more conical shaped than other caliber XTP's, maybe that is why it feeds well in all my 380's
My Kahr won't tolerate some FMJ's even, but it loves and XTP.
