S&w 629 4"
Last week I got a 4" S&W Model 629 for my new carry pistol in bear country. I've had a couple of Ruger Super Blackhawks in .44 magnum for 40 some years, but this is my first S&W in that caliber. The 245 grain hard cast lead bullets that I've been using for years in my Rugers also shoot well in this 629. I zeroed it to hit point of aim at 25 yards with those bullets, and it will also keep those bullets in light .44 Special loads on my 8" steel at 25 yards.
After I got it zeroed on my first day shooting it, I found a plate size piece of 4" thick concrete that I put on a stump. My first shot at 20 yards with one of my 245 grain full loads reduced that piece of concrete to airborne gravel.
I've only had it to the range twice and have only shot one box of full power .44 magnum loads and 1/2 box of .44 Special loads through it, but I haven't had that much fun shooting a pistol in years.
