That whole slide racking thing is a Hollywood escalating drama (yawn) thing.I lroll my eyes and gag when some military or police person in a movie,high stress tactical situation racks a slide to say "I'm serious now,no foolin..."
A hammer gun rests with the springs at rest.Hammerless requires stressed springs to be loaded.You watch practiced SASS shooters,they reload those doubles like an IPSC shooter changes mags on a 1911.It don't take long.And your 6 gun might be handy nearby.Depending on your home situation,it is also reasonable to keep it unloaded with a buttstock ammo cuff or a bandolier right with it.Loading is quick and silent.Its your 5 seconds,up to you.
I might prefer a Bennelli combat semi-auto if my job was looking for trouble,but,as many have said,defending your home,its a serious tool.
If you get a lot of practice as a cowboy shooter,it will be a fast,sharp tool
