Great in my sti 2011 - Atlas Gunworks Geppert X-Line Vario 1911 Standard Trigger

Great trigger, expect to do a little fitting. Atlas has great videos on their website explaing it. I tried a medium flat and it was a hair too long, got a medium curved shoe from a buddy, it's just right. I had to file the trigger opening in the frame for the flat one. Then had to file some more for the curved one. There was some work involved with cheap needle file, but my trigger feels great. Eliminated most of the takeup and overtravel, it won't change your pull weight, just the slop in the trigger. As a bonus, I'm good at taking my 2011 apart now.
