I taught my daughters how to shoot with a revolver first...mostly my old LAPD revolvers, which are DAO. A K-frame DAO with wadcutters is an excellent starting tool. We went on to semis later, if they wanted to. But the revolvers were the primary house guns, easily manipulated, accurate and utterly dependable. Too easy.

Later on, semi-autos were introduced. Revolvers are still the go-to guns around the house, though.
We also did some advanced stuff with 240Bs...
My youngest daughter is now an accomplished bullseye shooter and loves shooting anything different.
