My first Ruger back in the late '80's was a P-85 with the safety that subsequently went back for the recall. When the P-89DC came out, I traded the P-85 for it and have been happy with it ever since. I used to shoot competitions with the P-89DC in the early '90's, and used the decocker at the end of every round to show unloaded and clear. Never a problem. My favorite guns are my Sigs, all but one of which is the traditional DA/SA w/decocker, and none of them have ever failed. I also have a 1911 that I have carried cocked-n-locked, no problem. My most recent purchase was a CZ-75B Omega that I bought specifically for the decocker, which is great. I also have Glocks and Springfields that are striker-fired.
I guess you could say I prefer decockers, but I'm comfortable with anything.
