I shoot DA almost exclusively in practice. It takes practice, but it's not hard to do. I can roll the 6" plates pretty regular with a DA K frame at 25 yards. I even do pretty well on 'em with my 2" snubby .38. Now, when I'm shooting at a rabbit or something, it's SA. Heck, I carry single actions a lot when I'm outdoors. But, defensive shooting, you need to master DA shooting.
If you ever get a chance to watch a PPC shoot, take it. You'll be amazed at the accuracy a good DA revolver (usually custom race guns, of course) with a really good shooter can do. I was at a local match once when this guy who was ranked 18th in the country in PPC showed up to cherry pick once. He was pretty awesome to watch! This was one of the first matches I ever shot and they were allowing SA shooting at this match. I'd not quite mastered DA to be all that confident in it, yet, so I fired SA. This guy cleaned my clock shooting DA, LOL! That inspired me to learn. His gun was a beautiful race gun, too, built on a M10 Smith. When this shoot occured, S&W hadn't invented the L frame, yet, so that was a while back. They had a pretty good purse on this match and I took home third place money. This fellow and his friend took first and second, the rest of the shooters were locals. They were Wharton county sheriff's deputies, so I suppose they could use the supplemental income. LOL
It's really not that hard to learn DA shooting. You can learn in a fairly short time. You just need to practice sight alignment and trigger control. Pull the trigger through slowly increasing pressure on it and concentrate on adding the pressure progressively and slowly at first. Put your finger through the trigger to the first joint for proper DA control. Don't try to use the end of your trigger finger as you would shooting a bullseye match pistol or something. Do some dry fire practice trying to keep the sights aligned and keep them from bouncing around as you operate the trigger. Dry fire practice helps a lot.
