My Ruger LCP with 8rnd mag and Crimson Trace grip activated laser, rides in my front pocket in a Kydex holster every waking moment. Spare 8rnds on my hip. My "retrieval" time is 2-3 seconds or less. Depends if I'm walking around with my hand already in my pocket or not.

There is no "printing" that anyone would have a clue to what it is, with the holster.
Most folks simply are not that observant, you could walk around with your forehead on fire, and most wouldn't notice.

When I sit down at night for Tv time, weapon still in the holster lays on the end table next to me, again 2-3 seconds retrieval without getting up.
I run IDPA style live drills with said setup at least once per month, I should do it more often, but it doesn't happen.
I practice reloads as well at that time.
Then there is the dry fire drills I perform once or twice per week with the same gun. Works wonders, and only take's 5 minutes or so to do.
A second LCP w/ctl rides in the center console of our Pilot, and can be reached and retrieved with one hand still on the steering wheel in 2-4 seconds. I can do it by feel, without taking eyes off the road. From either the drivers or passenger seat.
My 2 cents worth of Monday quarterbacking... Cop went in the house, he had gotten away from the threat. Should have instead took up a position of defense in the house, he had already called 911, with the front door locked and not went back outside.
The fight you avoid is the fight you win.
