2 revolvers
.357 is OK
Bigger is better
For a woman a .357 is OK - .38 for practice
Always think of ear protection for practice - many later will agree -like my older brother who carries a Ruger .357
I’ve seen local LEOs carry a 40 pistol and a .357 revolver as backup
Nice iron I told them
But 2 in matched calibers are simpler and could save your life
I’m fortunate in that I can draw and have good accuracy with both hands - and at the same time
PRACTICE PRACTICE PRACTICE
KEEP YOUR BACK TO THE WALL
And don't watch TV westerns or shoot the lib news announcer!
