I had a Sig 226R DAK. It was a nice gun and perfectly reliable, I just couldn't get used to the long reset.
The trigger pull, while smooth, is just a little too heavy for me at 6.5lbs. It made follow up shots just a hair more difficult, especially when going for speed.
I weighed these negatives, and as much as I'd liked to have kept it, a Glock or a regular DA/SA Sig is just better FOR ME.
