My first SD weapon purchased with my money was a Sig P-230 in .380 which seemed to be an adequate SD round, easily concealable, affordable and felt good when I held it.
Unfortunately, it is the worst handgun I have ever purchased.
Every time I fired, it would take a little piece of my hand in token sacrifice. After the first day on the range, my wife thought I had been shot when I placed it on the table and blood was dripping onto that new little gun rug I had bought. It was/is accurate and did the job for a few months until I bought my second one.
