Not with so many better options available.
I voted NO. Even though I've shot a SA more (10x more) than any other type of handgun. Competed in SASS at a very high level for many years and feel very comfortable with a SA (shooting traditional/2 handed, duelist/one handed, or gunfighter/one in each hand). I'd say with all the options available, the SA handgun is better than only 3 options.
1) Derringer
2) Single shot
3) No pistol at all
I hate glocks, but carry a G23 because it has the fewest weak points from a self defense standpoint of any readily available handgun. I just wish I was as proficient with it as I am with a SA. I just need to wear one or two out, to get to that level.
BTW: Here is a video of me winning the Midwest Regional Cowboy Action SASS shootoff in 2005
