I have been pondering the thought of carrying concealed while working. I have over $60k in tools and equipment in my trailer. Last month while mowing, I found someone in my trailer about to steal something. Today was the deciding point to carry at all times since I live only 30 minutes from the Newtown School shooting. My question is who carries concealed while working and what is a good gun to carry that will stand up to the dirt and dust associated with landscaping/mowing and is small and comfortable enough to have while working?
