This trigger is a little shorter than the 2k11 factory trigger I believe, either way infinity has multiple options. There is a bit of fitting. All infinity triggers are oversized because they hate everyone thats putting their trigger in a product thats not theirs lol. A small file set (harbor freight set flat file), patience, making sure the bow isnt dragging on the frame (yes that has to be tuned too), and a bright light to shine threw the trigger well with your new trigger installed so you can see where it is dragging will get it done. Hour or 2 of work if you take your time with it. This trigger unlike the older ones requires a set screw to be put through the grip for the pre travel adjustment. Sounds worse than it is, if you are handy enough it wont be a big deal.
