Read up on your P380 and the ammo it likes, a lot of people complain about Fiocchi not working in their P380. Another thing I found about my P380 is its very problematic when it gets dirty, seems to give me problems after shooting a few boxes of ammo. I'll clean it and be good to go again for a few hundred rounds.

I also use a synthetic grease instead of oil, seems to stay in place better and provide better lubrication. I use the lube chart, but instead of oil, I use a product called superlube. Give it a try and see if that helps.

Don't give up on your little guy, once you get it going its a keeper.
