There are more guns out there for that, than you can imagine. Some of the ones I use are Charter Arms Bulldog, Ruger Speed Six 2-3/4", any of the six series are available in the same barrel length. Ruger SP101, Ruger LCR, I carry one in 357 mag. Take your pick with mags or +P. S&W 10, 15, 19, 13, 60, 64, 66, all good. Taurus 605, 856, 431, 441, 85, Some are 5 shot, some are 6. Colt Detective Special is nice to carry, but spendy, I like the 686 3" Plus which is a 7 shot. All of them perform the same function. Pick one and run it. If you have serious business I'd stick with a semi auto with one already up the tube. Just don't let it run dry. before changing mags.
Many of these guns are spendy. For price effective the Taurus or Charter Arms Bulldog.
