I have my Lightning .22 set up for targets, it now shootes a 5p size group @ 24yds (measured), prone, off the back of a balled fist (practice to start doing HFT
)
It is very hold sensitive, even after doing a full tune, including buttoned piston and adding a hamster and adding weight to total 13.5lbs, my next mods are to include a bolt through the barrel hinge instead of the pin, short stroke it and make a full custom stock for it
I find the best hold for mine is to rest it either on or in my hand about 50mm (2") infront of the trigger opening, very lightly hold the kneck so that the only real pressure comes from the trigger finger and only lightly put the butt against the shoulder
As for the trigger it does need a very good polish, aswell as the piston shoulder, and the sear retainer spring can be bent so its slightly softer , then its quite a good trigger.
