Welcome from the Midwest. I also bought my wife a Solo. Use the ammunition they suggest and it should be fine. If not send it back and Kimber will take care of it.
My wife saw a Sig Sauer p238 with Pink grips, and bought it yesterday. She said that maybe NOW I would leave her gun alone. I said yes I would and I guess I will just have to carry the SOLO myself Oh Boo Hoo. I had been carrying the Solo more than she.
