Hmm, I might just do that. I have a couple of dedicated light/summer jackets ( NOT Metro at all!
) that I use as cover garments during the summer. However, most of those experiences have been while going from home (air conditioned) to car (air conditioned) to starbucks/library/friends house (air conditioned). I was hoping for something I could carry without being scared to take off my jacket or shirt, if necessary (...it's Florida...). In the end, I might just IWB my G19, cover it w/ a t-shirt and call it a day.
