Manufacturers will plainly indicate on their packaging if the loads are +P or higher. Make sure your loads do not indicate +P or high pressure. The "standard" ammo referenced on here for practice and self defense, like Winchester White Box, S&B, Hornady CD, Gold Dots, etc. are standard pressure .380 loads.
I would also be leery of hand loads unless you've done them yourself.
Others will jump in here and clarify!
