If buying today I'd get an 8 shot 357 snub.
Colt DS and 2.75" Security Six are my small revolvers.

My M59 is the only gun I've had to draw or carry in my hand when on the water or working thru the night in boat yards.
Switched from my Colt GM and HS 22mag Derringer to the M59 and Derringer the first time a boatload of refugees washed up on shore, in the Keys, when on my weekly solo fishing trips.

When assisting Customs or DEA with their Marine Electronics I knew they'd protect me so I just carried donuts and fresh coffee.
