And I even hear revolver guys describe the single action pull of a da/sa revolver in comparison to a 1911.
The SA trigger on my S&W69 (5-shot DA/SA .44mag), after a trigger job, is even better than the trigger on my 10mm 1911 Kimber Eclipse (also after a trigger job). I had previously set the trigger of my 1911 at 2-1/2lbs, quite a while ago, but recently I got a hammer-follow (down to half-cock) at the range, when I was chambering a first round. That's normally prevented by the fact that I stay off the grip-lever while chambering the first round (and in all other handling, except when actually ready to shoot), but I had tested it right after I set it at 2-1/2lbs for hammer-follow WITH the grip-lever compressed, just in case someone else who might be shooting my gun chambered that way, and it was OK. But recently, I had to increase my recoil spring to 20 lbs,from the stock 18.5 lbs (because I was seeing some excessive wear on my gun), and that apparently causes the slide to slam home enough harder to cause the hammer-follow. And apparently I wasn't completely off the grip-lever after all, or it couldn't have hammer-followed, regardless of how hard the slide slammed home. I think other contributing factors were that all the sear spring legs had weakened just a bit over time (including the leg that pushes the grip-lever aft) ... the trigger had decreased to about 2-1/4 lbs, and the grip-lever didn't resist being compressed as much as before. So I increased the trigger to about 3 lbs, and haven't been able to provoke a hammer-follow since then. It's still a very nice 1911 trigger, though.
My M69's trigger is at 2-1/2 lbs, and it feels better than my 1911 did, even when the 1911 was down at 2-1/4 lbs. I think maybe the reason is that revolver triggers can have zero "take-up" ... the trigger can be touching the sear before you even touch the trigger, and a semi-auto (even a 1911) has to have a least a little take-up, to prevent hammer-follow, and to allow proper trigger resetting. And on a 1911, compared to a revolver, there's just some other stuff involved in addition to the trigger, sear, and hammer (like the disconnector) ... more opportunities for some extra "play" here and there. But I DO think 1911 triggers, especially after a good trigger job to smooth and lighten the trigger, are lots better than any other semi-auto.
