It's a topic that's played out here lately (if you judge on the thread title alone, but you're asking a different question). The 1/16" of rearward travel is normal; at least it is on my 2011 model 700 with the X mark. As far as I know, when shopping for aftermarket 700 triggers, you only get one or two options per manufacturer for the short n' long actions. This suggests that yes... they'll all fit. FWIW... I went with a Jewell. It's awesome at 2 lbs.
