I think the HK VP70 had a sliding trigger, and was double-action only. However, it was striker-fired, rather than hammer-fired. From all reports I've seen, it's an unusually long and heavy trigger pull. I don't know of any hammer-fired DA/SA or DAO pistols with straight-pull triggers, offhand.
I'm in what I predict is going to be the minority that likes pivoting triggers, but it's probably more that I prefer specific pistols that they are found on to 1911s generally, for various reasons, than that I care how the trigger is articulated, as such.
Having said that, wally articulated very well why the straight-pull trigger of the 1911 is so popular, and why it is tough to get a pivoting trigger to have a pull as nice as a 1911.
