Seems clear that: a bullet with zero energy (ie, just layin' there) has no ability to do damage; a bullet that's zipping along with ~100 ft-lbs of energy can't compare to effects of one with ~400 ft-lbs of energy; a bullet that still retains energy after exiting a barrier hasn't spent its energy yet; and a bullet that has no energy left prior to exiting a barrier has spent all its energy inside the medium. Call it energy "transfer" or whatever, that energy has to go somewhere, and it doesn't all "disappear" as frictional heat.
I feel that the recent shooting in NYC in front of the Empire State building makes a great case for NOT carrying FMJ in an urban environment.
The rush to blame the two officers for lousy aim was proven somewhat wrong, considering the perp was hit ten out of 14 rounds. So most of the wounded bystanders were hit by 9mms doing a total penetration through the BG. Ergo, they mostly by these through and through rounds.
And I really wish that the news media would stop blaming the LEOs for bad shootings without being there or understanding the first thing about gunfights.

Carry hollow points. I see no reason to carry FMJ.
Give ya an example-
A 200 pound guy stands on a platform that is 5 feet high and jumps to the ground twice. In both instances, he will have the same kinetic energy and the same momentum.
The first time he does so, he bends his legs as he lands. He is uninjured.
The second time he does so, he locks his knees and remains stiff-legged as he lands. Obviously, he sustains injury to his knees, ankles and hips.
It's all about time- and strain-rate dependence and hitting something "important".

There's nothing wrong with carrying FMJs if that's your preference.
Personally, I use Gold Dot and Critical Defense for my carry and HD handguns, I would definitely recommend them.

You guys still aren't grasping that the energy transfer means nothing to the target.
Assume a bullet expands to .60" and does not exit the body resulting in total "energy transfer"
Are you guys actually convinced that's more effective than a bullet that expands slightly less say .55" that makes it all the way through?
Energy is merely bullet fuel. It does nothing by itself as its released into the body. My vest analogy is valid, the armor wearer indeed experiences as much energy transfer as is possible with soft armor yet comes out completely unimpaired
I'll stick to HPs except for in my LCP during the colder months where I switch to FMJ flat points.

Ive had FMJ underpenetrate a few times, and had JHP overpenetrate a few. At the end of the day, i carry JHP because it was designed to expand and cause more tissue damage. With FMJ its much more likely to pass through. In a SD situation, I think its better that a HP underperform and for me to die than for a FMJ round to pass through and hit a bystander. just my opinion.
My take is just as long as you know what is behind your intended target then yes it is OK to use ball ammo. Now in a zombie apocolypse scenario, we all are hoping that when shooting ball ammo, it will go through 2 or 3 or more with one shot destroying and killing them !!! God Bless
"And I really wish that the news media would stop blaming the LEOs for bad shootings without being there or understanding the first thing about gunfights."
I tend to agree. What would have been the public and media response if the LEOs hadn't fired because the "streets were crowded" and this guy opened fire? Me? I'm not voluntarily dieing because someone happens to be in the background.

Fmj is generally preferred if shooting smaller calibers-22lr,25acp,32acp in particular if winter heavy clothing.
Even a 380 has below min fbi stat penetration if jhp is used.That said even 32 acp can have or meet that 12 in min with correct ammo with fmj.
Bullet placement and yes can be over penetration with hand cannons of large caliber with fmj yet it is what armies are limited to,possibly one of the several reasons they went to smaller calibers.
I shoot same ammo for practice as carry and dont use zombie rounds or any of the frag rounds as they dont often expand or preform as intended.I keep one jhp in tube rest are fmj,yes 32 acp.Backups is pt22 22lr.,25acp Titan,peashooters all over the place can reach one with either hand front or back.
Im small cant hide a large pistol,have a truck to carry the 45.
