If I needed the gun and had the time, I'd probably cock my A/S. But to be honest - once ya break the trigger in (its rough until after 200-400 rounds), the DA is still very nice.
When I have done the contest shooting in the Internet Matches we previously shot here on the site, I've done it with the SA pull. But, the DA pull is still much lighter than the DA pull on say - a Beretta 92 or some other DA/SA gun. Its very smooth, and not that heavy.
I wouldn't be able to shoot the un quite as well if I had the QA version, because ya don't have that nice SA pull on the QA.
