I carry a S&W 642 as an EDC for a couple of reasons. I commute by bicycle 90% of the time, so having two hands to manipulate the gun is out of the question during this time. I ride in urban and rural areas, so I like the option of carrying shotshells in my first cylinder on rural rides because dogs are my most likely aggressors. On the bike I carry in a Survival Sheath Systems chest holster, which puts the revolver in the center of my chest with the muzzle pointing at my left shoulder and the grip angled toward my right hand. It also helps keep the sweat off the gun by being out front in the wind during the ride. Off the bike it is carried using a Barami Hip Grip over my appendix. This grip holds the revolver solid enough that I can run with it in my waistband.
