I've got an S&W model 29 6'' with the partially rifled barrel. After sighting it in, I hit the centre of the target bull at approx 6 yds with the first shot.
That’s not bad .. wonder how that converts to a 25 yard full bore target ??
As a comparison, my S&W 38 special model 52-2 semi auto target pistol came with a test card group of less than 1” @ 50yds. Achieving this in real world conditions was, for me, impossible.
