I’ve bought 2 new S&W’s in the past 5 or so years, both had to go back for barrel alignments.
A 629 Classic 5” and a 442. If I remember correctly the 629 was shooting about 5 or 6 inches to the left with the rear sight moved as far right as it would go. At 25 yards.
But while it was being repaired I bought another 629-4 Classic 5” from a buddy. So when I got the repaired one back I sold it to another buddy and I think he’s only shot it 12 times in his back yard. So I really can’t comment on how the repair went.
The 442 was the same way, 5 or 6 inches to the left. And this was at 25’ and with 6 or 8 different loads. After the repair it shoots everything good and at the point of aim.
