For starters, does the standard 92FS fit the 92G Elite?
Do you mean by that do the magazines fit ? yes. Holster ? no, the E/E2 use the Brigadier (heavy) slide. Leather is not as easy to come by for Brig slide models...
what's the difference between the Elite and Elite II versions?
E2's have the 92/6 D model trigger spring, for better trigger pull., and extended magazine release, Inox slide / ss barell, black target sights (replaceable), serrations on the front of the slide, & checkering on the front & back of the grip.
I have the 96E2, it's a really nice shooter.
