Don't really know about the "new" 800X trigger, - but if you can install a GRT-III trigger, do it. Then, use the gun for awhile, maybe 1000-2000 shots or so. After that, put a few bucks aside, and have Gene do a "Turbo Tune" on it. - Trust me, you're gonna LOVE that 800X. - A complete tack driver, ...

... Goes without saying, I have one, and have done that - and it's "quite a gun".
