NONE of u have a CLUE, so a REAL
handgunner will tell you. The aluminum jacketed 85 gr 380 bullet was "looked at' by Winchester for loading in the 9mm. However, it has feeding problems in some guns, notably the Browning High Power, it "fouls" the gas ports in HK squeeze cockers, and it lacked "adequate penetration' in the room temp, 20% jello used for testing (at the time).
