I have started looking for for a single stack 9mm for concealed carry. I have a service sized Springfield XD 9mm for home defense, but it is too big and cumbersome to carry. I'm currently looking at the following 2 guns:

1) Ruger LC9
2) Smith & Wesson M&P Shield

What are your thoughts? Any other guns I should be considering?
