It’s the only thing that really matters. Very few pistol manufacturers make a product that I’d stake my life on. Yours is one of them. S&W revolvers are another. My 629 is my go-to when ATV-ing or traveling through the woods.
Our 4” 629 is favorite of Mrs. L. I load her a 210 grain JHP at about 1,200 fps. Very controllable but plenty of power.
