New to 9mm LF Home Def Ammo

Hello all,

I am selling off my .40s and moving to the 9mm. I have always heard stories that the 9's are piercing through walls in homes. Is there a few good 9mm Rounds that I can use that are less likely to go through and through?

All pistol rounds are bad about piercing multiple walls, often penetrating 10 or more sheets of drywall before stopping, its a characteristic of the breed. There is no ammo on the market that is an adequate self defense round that doesn't do that, most of the ones that claim they don't penetrate as many walls are either flat out lying in their advertising or their penetration is so poor they aren't suitable self defense rounds.

Rifles are even worse than pistols on over penetration, shotguns when loaded with slugs or buckshot are also bad about over penetration.

The only sure cure is to hit your target.

I'm not quite sure what the "LF" in "9mm LF Home Def Ammo" is.

Basically what G56 said. If it penetrates bad guys it will penetrate walls. If it won't penetrate walls then it won't penetrate bad guys. This means that the .40 has the same problem.

Just pick something off DocGKR's list that both you and your pistol like.

LF = Looking For

Been using it so long, never paid attention to if people knew or did not know its meaning.

Thank you all for the information. During my Time in the Corps, we where one of the Last Units 1992-1997 that still had .45. I carried an old Singer built model, while we also had a frame stamped Colt 1913. So all my training was spent shooting them, and I never really cared much about ballistics.

Fast-forward to now, my daughter simply can not shoot anything over a 9mm due to a double jointed issue with her elbow.

I am now in that point in my life I finally have the extra time to research and learn about this.

Thank you for all your feedback. It is most appreciated.

Cool ammo

the least penetration in test I have seen is fed guard dog they expand with 9 or 10 inches max average.

I was beginning to wonder if you meant "Lead Free", but "Looking For" makes perfect sense now.

If you follow the DocGKR link from above he has several other stickies posted that explain the basics of incapacitation and terminal ballistics and how and why bullets are tested.

Good luck to you and your daughter.

Thank you all for the replies. You have all caused me to due way to much reading during cough cough work time.

After going through much information, I decided to keep the .40 and buy the S&W 9mm barrel and Mags instead, $75 barrel and $75 for 3 mags is not a bad deal.

Daughter has the M&P9C and I have the .40Full, with the 9mm barrel coming next week.

Now I just need to sell me Kimber .45 for an M&P .45.

Thank you again, and I am sure more question to come.

No such round. Any round, 9mm through .45 that will penetrate a bad guy and cause enough damage to stop him will penetrate walls.

You might want to consider getting an aftermarket conversion barrel instead of a 9mm factory barrel. While the factory barrel will fit, it doesn't lock up properly. If you do a search on this issue on this forum you will pics that show why a factory barrel replacement might not be a good idea. Hope this helps!

I did read a lot of the post. Also read a bunch on the Smth and Wesson forum as well as ar15 and another. Seems to be a theme that barrel swapped sixing has changed around 2012 or 2013. One person showed 3 barrels and a micrometer. I figure, if it does not work, I can send it back.

New Barrel came in on Thursday. We ran 4 different brands of ammo through it today. 400 rounds later no jams.
