    As an intellectual exercise, if you were limited to FMJ rounds for self-defense, what weight would you pick. Given that expansion isn't going to happen, I'm not sure how to evaluate speed. Is bigger better then? 147? 124? 115?

    OP was about FMJ, not JHPs.

    I would go as light as possible since it is still going to overpenetrate way more than is desired but at least it won't overpenetrate as much as the heavier bullet.

    If I had to go FMJ in 9mm it would be 147g Lawman. It has a flat nose instead of a round nose.

    Whichever one is the least likely to pass entirely through an attacker's body. I don't know which one that might be but I'd guess 115-grain, if bullet weight actually trumps velocity as I keep reading.

    IF I were forced to use FMJ, I would be selling the 9mm & getting a 45acp isnstead. If you are stuck on the 9mm w/ FMJ, then the heaviest FPFMJ you can find. The light & fast ones are just leaving the BG body faster.

    Federal American Eagle 147gr truncated cone flat tip or Speer Lawman equivalent; Fiocchi NATO spec. 147gr subsonic; reliable brand made NATO spec. 124gr (domestic or foreign)

    most likely 115gr will be most available to U.S. civilians in a SHTF scenario

    Probably won't make much of a difference. You're talking 24" inches of penetration on gel with any of them. A flat nose might be best but probably not by much.

    If I had to choose 9mm ball this would be my choice also.

    147, just because I like the recoil better. As far as the other end, it makes no difference. Just poking holes, and they are all the same diameter.

    Fiocchi makes a 124gr truncated almost pointed, round. They used to make a 123gr flat point that was really hot. I have some still. Incredible ammo.

    If you cant find that, lawman has a 147gr flat point.

    Other than potential penetration depth there is not much difference amongst the three weights of the 9mm FMJs.

    In soft tissue, the 115 gr. FMJRN at 1155 fps is good for about 26.5 inches of penetration, the 124 gr. FMJRN at 1120 fps will be good for about 28 inches of penetration and the 147 gr. FMJTC at 1000 fps will reach a depth of about 32 inches.

    None of the 9mm FMJs will damage much tissue as they traverse soft tissue and all of them will have the tendency to exit an assailant, regardless of the angle at which they strike.

    While I typically prefer heavy-for-caliber projectiles ("light & fast" projectiles have their utility, too), in this particular case, there is little to be gained (except for greater penetration) from that preference.

    I don't really see why anyone would care when it came to FMJ's for self defense since they will all make the exact same wound, but I guess I would use 115g simply due to less penetration.
