I am a S&W revolver guy. My EDC is a M-13 3" with the old FBI load. My Better-half just finished her CCW class. She shoots my Smiths well but is not the gun nut that I am. We went CCW shopping earlier this week and she decided on a Ruger LCP .380 with the Crimson Trace lazer sight. (She shoots my Kahr MK9 and PM9 well but finds the slide springs hard to manipulate.) At any rate, it is her money and her choice and she wants the LCP .380. Now my question: What is the best SD round, the 90 gr or heavier? I am not interested in a discussion of the limited effect of the .380........for what she wants it for it will do. Just want suggestions on the best .380 round. Any suggestions will be appreciated. Thanks for your input.
