So I was wanting to get some suggestions of guns that I should look at. I am looking for a piece that I can carry at work, business casual, and everyday carry. I have a young son so I want a pistol with an ambidextrous thumb safety (I don't like the idea of him climbing on me or me carrying him with a fun that doesn't have a safety). I am medium build but would like a full size 9mm if it possible to conceal. I have looked at the px4 and the XDM. Thanks for any suggestions. I hope to get out to the range and rent some of the guns before choosing one.
