A 25 is better than nothing. But the Ravens, Jennings and Bryco guns were not safe to carry a chambered round in. If it is all she has, then it is all she has. But if you have a couple hundred dollars to spend you can find something better. I would be looking for a snub nosed revolver in 38. You could find an EAA Windicator used for under $200 if you shop around.
I am not going to tell someone not to carry the only gun that they can afford. If it is all you have...don't carry a round in the chamber. If you can afford to get something better...you should do it.
Romans 1:16 I am not ashamed of the gospel, because it is the power of God for the salvation of everyone who believes: first for the Jew, then for the Gentile.
