Underwood Extreme Penetrator 10mm for home defense - Concern

[Triathloncoach]

I am considering this as a home defense round, not sure of the bullet weight. The website says that sheetrock, sheet metal, windshields and wall boards will not effect penetration.  For obvious reasons this concerns me.  Your thoughts please?

Thank you

That's pretty much any round. Maybe a fragmenting round would be better if you are trying to get around those.

If you're concerned about excessive power or penetration, quit looking at Underwood's offerings. Almost any 10mm round will have a significant impact increase over most any other defense caliber, and going to the "full power" supplier will exaggerate that, often to an extreme. If you live in an apartment or other close quarter type setting and have these concerns, a frangible, traditional HP, or lesser powered caliber may be a better option for you.

I strongly urge you to consider a different round for home defense. 
Don't misunderstand; I like underwood ammunition.  However, he has several JHP rounds
that are far better choices for your specific application.  There are other fine and
better JHP choices from other manufactures as well.
That UW projectile will go through several walls, then about 36" of ballistics gel before stopping.
Unless you live in close proximity to polar bears, it's among the worst 10mm home defense choices
possible IMHO.

Please locate gel test of that particular round provided by Raggedyman on this site for illustration.  He's provided a bonanza of 10mm gel tests.

Not good for home defense.My 2 cents.

Thanks guys.  I'm gonna stick with my Glock 19.  Two of my upstairs bedrooms have kids in them.

It's not a caliber thing. You could fare well with a DRT or Sinterfire round in either caliber. I'm told Air Marshalls use Sinterfire rounds to keep them from exiting the plane.

Concur...the Extreme Penetrator would not be the choice for home protection if you are concerned about it over-penetrating.

I would stick with something like this for home defense if one was concerned with penetration:

The wrong 9mm will penetrate sheetrock. Be careful.

[Intercooler]

Just about anything will penetrate sheetrock. It would probably have a hard time stopping a BB.

If the time comes that you have a gunfight in your home, you need to have thought out fields of fire ahead of time.  You need to have your defensive positions set up so shots coming AT you that hopefully miss will not endanger loved ones, as well as providing you a field of fire towards the target that is likewise devoid of anything you are concerned about destroying.

The rules of safety still apply in a gun fight...don't point your gun at anything you aren't willing to destroy and be sure of your target and what is beyond it.

No need for a penetrator round if penetration is a concern. I would recommend light for caliber loads like 115 grain 9mm or 155 grain 10mm. Also, frangible ammo. Any and all ammo will over penetrate a bit but we can minimize it.
