The fact that old discussions are all here to click and read, and possibly reply to, is the BEST feature of online forums, as opposed to social media, where interesting stuff flows downstream in a day or three, never to be seen again.Spring guns sometimes take years to reveal all there is to know, good and bad. So it's all well and good that discussions sometimes run for years.Over time I have seen many Quattro-triggered Hatsans, for sale and otherwise, with the comment: "The trigger snapped and has been replaced". These are not isolated incidences, really.My H135 trigger is still in one piece, but I did buy a cast bronze replacement trigger, by a Russian guy, waiting for the day when the snap happens.
