I have a few snub revolvers that are my go-to carry, as well as home defense weapons.
A big reason why is that they are very easy to carry, so they are not a burden to have on me all the time, even at home. I've come across a lot of video footage of attackers waiting outside to ambush the homeowner when they step outside, so anytime I let the dog out(multiple times a night), take out the trash, get the mail or whatever, I want to be armed.
Another advantage of the snubby is they are very reliable in any type of contact scenario. Most people think home defense always involves time and distant being on their side, so default to long guns, but I view it somewhat differently. Possible scenarios would be the examples I already listed, but also any situation where you feel the need to check out a noise you think is nothing, but could potentially be an intruder lying in wait and a close-quarter ambush is possible. And don't rule out intruders gaining access to your home quickly and rushing you. That actually happens quite frequently from what I've seen. I do want to avoid shooting anyone if I can help it, so retreating into the interior of the home putting locked doors between us and them and making it into the safe room with police on the way would be ideal. It may be possible or it may not. From there any shots fired would be from a few feet max.
I do own several high capacity 9mm Glocks and in situations where I may have some time and distance on my side, I might choose one of them, but I wouldn't feel all that undergunned with just the revolvers.
