I had one of these to fettle for a neighbour in .22. The trigger can be improved with the addition of a slightly longer M3 adjuster screw and once polished I was getting clover leaf groups at 25yds, so not too bad. The only thing with the Hatsan springers is that they're all FAC capable, so transfer porting is generally larger than required for sub 12fpe, as is the bulk of the piston, which can make them a little slammy on cycle.
