whatever your gun will cycle... hollow points are hollow points to a large extent... reliability means a whole lot more than how much damage they cause. id rather be able to fire off 6 fmjs without a failure than 1 hollow point that wont feed.

Me and my brother did some 380 ammo testing last fall. I have always been a huge fan of the Speer Gold Dot in every caliber I have ever tested it in.........until we tried it in a 380. We absolutely could not get it to open up reliably at all. Hands down the best we tested was the Winchester PDX1. Those performed perfectly every single shot.
Here is a pic of the two loads we tested that day. The two on the bottom are Speer Gold Dots. The one on the top is the Winchester PDX1. All the Gold Dots we recovered look similar to those two and all the PDX1's we recovered looked like that one. In the past I have tested other 380's but none have ever been as reliable as the PDX1. I will also say the 380 has produced more of what I would consider "bullet failures" than any caliber I have ever played with.
