If you can get your money back, do.
There are two .380s in my house--a Bersa Thunder and Walther PK. The first was new and right around $250, the second was barely used and about the same. I didn't like the action on the Bersa, so my husband carries it. The Walther is an absolute dream and I don't know how I lived without it.
I have no doubt you could find a really good weapon even on such a limited budget.
Our prime purpose in this life is to help others. And if you can't help them, at least don't hurt them.--The Dalai Lama
