Sotware, not Hardware

I have a 9mm XD that I want to use as a house gun for an apartment, and my gf is getting a 9mm soon for the same purpose. We would like lower recoil rounds, that have only as much penetration as neccesary. I know that rounds can still penetrate no matter what, but I'd like to eliminate as much of that possibility as possible.
Software.
I would first consider prudent steps to avoid being in Serious Situation.
Beefing up Security and at the same time making yourselves less of a target.
Shooting lanes, such as furniture placement allows you and her cover from incoming rounds and backstops for your outgoing rounds.
Training classes that include, but not limited to guns, loads, gun fit, correct basic fundamental, Reliability, Shot Placement...
Here is the deal, with Shot Placement, one has to have rounds designed for the gun, that work Reliably with mags, that shoot POA/POI.
If a load does not run the gun, with mags, it for sure cannot shoot POA/POI, no matter what the box or marketing "says".
Once dead, a little too late to consider the load did not run the gun.
Hardware
Once the Software above has been done, Actually apply to using guns, ammo, and running the gun with instructor.
Continue with quality practice.
Software first, then apply with Hardware, then these both in conjunction.
The Motion light might deter, a beefed up door chain/bar might prevent.
Worse comes to worse, the practiced plans incorporating training with Cover, Shooting lanes, You hit what needs hitting to stop that threat as quickly a can.
The load could be anything, even hardball, if the Software was applied and that Bookcase moved "there" or that top drawer filled with books over "there" or...Aquarium place "there"...or...
I do not recommend fru-fru rounds, those with umbrellas, stir sticks or low calorie marketing.
