First off, I don’t recommend carrying a defensive handgun
in a pocket, but in a holster, same place, every day, dressing for concealment, and training frequently to draw and fire to a high degree of proficiency. Like your life depended on it.
If you insist upon a wheel gun the Charter Arms “Bulldog”
with a bobbed hammer, 3” barrel, in .44 SPECIAL is THE way to go...no two ways about it.
Now your talking, pardner. Except I’d go for a 3” model 24 in a high ride foward cant holster slightly behind the hip. I have some 44 handloads with 210 gr. hollowpoints that travel out of the 3” tube right at 1100 fps. Stout but not unmanageable at all. A 3” 624 has a lot to give in the way of service. I have one of each for CC, the 624 has been professionally dehorned.l
