I am a big fan of the DA/SA trigger on my Sig P229, but the gun is a bit large/heavy for me to actually carry it daily. If I had to pick a DA trigger for carry, you would first need to define what DA really is. A Glock is partially cocked, so pulling the trigger is technically performing a "double action" to finish off the cocking and release the striker/firing pin. Then there are systems like H&K's LEM trigger. It's fully pre-cocked, but the hammer is still down and it functions like a DAO revolver, only with a much lighter trigger pull. It works by having a cam mechanism engage the pre-cocked hammer spring at the last second, so basically you're pulling the hammer back as you pull the trigger, but it catches internally last second and comes down with all of the force that was stored by the hammer spring. Really neat system, but the downside is that it has a lot of take-up on the initial pull. Kahr probably makes my favorite feeling DAO type trigger for a carry gun, but I dislike Kahrs for other reasons so I won't ever carry one.
Lots of options out there for DA triggers...
