Consider the Sig P290RS
I have a Sig P290RS. It is the newer version of the P290. I love it. It shoots VERY accurately. Easy to fire with 9 mm or +P. Very easy to pocket carry. It comes with 6 and 8 round mags, so you can carry 6+1 or 8+1. Very nice gun. Flat and easy to carry, but very good shooter.
