Lots of people run a J-frame as their only defensive carry gun. With training, good ammo, and reloading practice (I adore Bianchi strips) they're an effective option that statistically will get you through almost any civilian gunfight!
You folks are making my sickness for the Chief Special worse!
I have everything in the world to carry, but I still carry the Model 60 I have had for years. I know that i should probably be carrying more gun, but the Chief continues to be the gun that I go to!
