I currently carry Speer Gold Dot 9mm 115gr as my self defense ammo. One concern I have about using this ammo for home defense is over penetration. Would the 124gr or 147gr be less likely to over penetrate? I originally started using the 115gr weight because, my primary practice ammo is 115gr, but a different brand (Rem UMC 115gr FMJ). I use this practice ammo since I can get it for around 12 cents a round as opposed to my self defense ammo cost of 75 cents a round. I still practice with the Gold Dot once every 2 months, shooting a box of 20.
Will the bullet weight make much of a difference?
