"Seaman, I have to disagree with you on the glock triggers being the best of the polymer guns. "
I believe I gave that designation to the Walther PPS.
"While trigger control is important, I'd say grip is actually more important"
This has not been my experience. Choosing a CCW gun I had it down to the Walther P99 and SA XDm, and chose the P99 chiefly because of grip comfort, pointability, etc. What a mistake. Despite the heavenly feel of the P99, my Tokarev (too small bar-of-soap grip), my PPK (can only get 3 and half fingers on the grip), or my Sig P239 (top heavy brick, akward doesn't-feel-right grip) all shot 3/4" groups for me....the P99, well, I had way more fliers than bullseyes.
Nowadays, I just shoot a gun and if in the first mag or cylinder it gives me a tight group I keep it, and I have noticed one thing about the keepers - they all have excellent triggers.
"...I think EVERYONE prefers an action [trigger] that is smooth with a clean, crisp break and minimal over travel."
Sounds like a good universal definition to me.
"The Kahrs are very smooth..."
Yes they are and of the new crop of l-o-n-g pull DAO handguns they are the best, but still to slow for me, the first pull on the Sig P239 is heavy, long and smooth, but but thankfully it is followed by subsequent quick SA pulls.
"As for rapid fire accuracy with a DA revolver, assuming the trigger is decently clean/smooth, rapid accurate fire isn't difficult..."
I stage my DA shots, but am still less accurate in DA (and can only admire good DA shooters), have carried S&W Js, Ks and Ns, but all have been DA/SA, at CCW distances my DA shooting is acceptable, still prefer an SA trigger option.
