Would a m&p9c be too big for a back up gun?

Hello everyone. I'm considering either a snub nose revolver or a sub compact of some sort for a edc back up gun and was looking for some input. I'm leaning towards the 9c since it doesn't seem to be much bigger but it might be bulkier then I realize to carry every day. Thank you for your time. via /r/CCW http://ift.tt/2p1yPpr
