it's a real DAO, and with a wonderful 6.5# pull
Yes okay, so I wouldn't discount it outright because of that, but my own experience with the relatively long and somewhat stout DAO trigger on a small gun (K40) is that my weak hand needed quite a good bit of shooting to get a LOT less weak, AND I had to learn to shoot with half my trigger finger wrapped around the trigger. Totally new kind of handling needed.
Then there was the matter of presenting the gun then starting the trigger cycle. Initially, it felt like (and was) a two-step process that took too long. For me, and I'm just saying that again, for ME it was a good 1,500 rds of shooting before gun and shooter behaved like a team. That learning seems to rapidly fade, too, given 95% of my shooting is with medium to full-size SA guns. I seldom ever shoot the 629 in double-action either, as it's strictly a range toy and not remotely intended for personal protection.
