SIMP, I was in your same situation a few months ago, my usual carry was my LCP and I wanted something a little beeferier. I purchased a Shield 40 in Aug and I positively enjoy this gun. I walked in to my LGS one day after I nailed a job interview and decided to treat myself.
The Shield is a huge improvement over the LCP in shooting enjoyment. The LCP kicks like a mule, so my practice with it is limited to 1 or 2 mags each range visit.
I bought a Barsony belt slide OWB holster off EBay for my Shield that is a very good holster, it holds my Shield securely flush against my waist at 4 o'clock. It allows for a easy draw in a bad situation.
Now with the Shield your only packing 6+1 in the 40. The other compacts out there will give your a few more rounds per mag, but they are going to be fatter then a single stack like the Shield or XDs.
Just my thoughts and musings, take them for what they are worth.
I don't have a good signature.....
