I have a widow friend who wants recommendations for a good home defense round for her Glock. She lives alone in a standard wood frame and sheetrock dwelling. She has several acres and her nearest neighbor is 100 yards away.
I think any of the 115 +P hollow points from a top manufacturer are the best place to start. Cor-Bon and Triton both make +P that is close to the +P+ ammo. If +P is to much for your neighbor for some reason then stick with 115 gr hollow points or maybe 124 grain hollow points.
"Of those that will penetrate, the edge is always with the bigger bullet."
While a Frangible type could be "nieghbor friendly" why worry, just don't miss
My neighbor's are less than 100 FEET, and we have normal walls around here too, but that's still a few walls, and some fencing to get through, if the worse case scenario occurred.
Personally, I don't have ANY experience with the Federal EPFMJ, but I have a feeling that it's probably one of the best choices available for a consistent expander, and reliable feeder.
In a Glock, feeding should never be an issue, but ya just never know...
I use the Federal 9BPLE's (115gr +P+) for my 9mm defense rounds, and the P9HS3G HydraShok 124 +P+'s are also worthwile, but for someone that's recoil sensitive, they might be harsh.
I don't have any question that the 9BP (115 gr HydraShok) will get things done, but when it all comes down to it, I'd rather know I have something that is "tested" and the 9BPLE is "tested".
Moving away from Federal & the HydraShok's, I would highly recommend any Gold Dot +P in any caliber... They are probably superior to the Federal's in terms of consistency in expansion, and penetrate well...
If Frangible's are the way to go, look at Triton, they have some excellent products. The Glaser's, Corbon Bee-Safe's, and MagSafe's are nice, but personally, I would go with Triton.
Did I mention a Shotgun, with Surefire foreend is the Better Tool for the job
Practice is the key--unless you can hit what you wish to hit--under stress, the kind of ammo is the least of the problems.
I would suggest, if this were one of my kids, and the firearm described is to be used: Practice with NATO ball, either Winchester or Federal. If memory serves, this is 124 gr. [about 1250fps from a Glock 17] POI is very close to 124gr +P self defense ammo, and the noise and recoil signature should be similar. A headset, reactive should be kept with the handgun.
If a frangible ammo would be better--at least 100 rounds should be put thru the gun. POI at close range [five to seven yards] will change very little.
Last, the lady should have a plan, complete with cell phone in safe room, locked sleeping room, outside of house properly set up, etc, etc, etc.
This subject is much more complicated than just ammo!!!!! GLV
