I'd be willing to bet that you could also reshape the hammer sear to have less of a flat spot on top to drag, make it more of a point instead of a mesa so the hammer would clear the sear sooner. I like your thinking on cutting a groove in the hammer as well, or maybe just a flat spot starting a couple mm's aft of the sear catch on the hammer, that could easily be done by the home tuner with a file and a little patience. Funny thing is I don't remember these issues with the 2260 or even the 2240 trigger group which is also similar, it seems like the 2260 would have exactly the same issues...it's the same trigger group afterall. The lower link mod would tend to increase sear drag because what you have effectively done by changing the fulcrum on the lower link is given the trigger blade more mechanical advantage. Mechanical advantage comes at a price though, you change the ratio of sear movement to trigger blade movement...easier to pull, but less change in hammer sear movement, perhaps worse drag issues. Honestly I think if the TKO trigger is adjusted right and you "squeeze" the trigger everytime (I try not to jerk a trigger anyways) then your FPS should stay fairly consistant. I installed the TKO kit, adjusted it, and forgot about it. I still haven't chronied my Disco, but to be honest it hits everything I point it at out to 60-70 yards or so, so I'm not really concerned with how it does on the chrony. The chrony would probably just make me sick to my stomach, haha!! Ignorance is bliss sometimes, and for me this is one of those times:) I still stand by what I said about the Disco trigger group when I first saw that they used the 2260 trigger, it is one of the worst trigger groups I have ever seen....but it can be made a whole bunch better, it is what it is. Looks like Crosman pulled out all of the stops on the new Marauder trigger, I guess they were saving that for a rainy day.
