Hi from Delaware and welcome to the Forum. When you get to the gun store pick up the weapons you are thinking about, go with the one that feels the best in your hand. It would be best to try to get to a range and test fire the ones your seriously considering, then make up your mind.
I did all of my looking around and had decided on a Glock 23, but when I got to the store it didn't feel right. I went with the Springfield Armory XD40 Sub Compact. It was a good decision, trustworthy, accurate, easy to strip and clean.
Get the one that speaks to you!
