Cool link!It'd be extra cool if anyone here had first-hand experience on these replacement triggers. They look cast, like the OEM triggers, not machined. Even strong-metal castings can fail due to internal hollows / stresses etc., and with trigger system parts, extremely minute differences in geometry have a big impact on function. About older and newer Hatsans, a pretty solid case can be made that post-2015-16 Hatsans are a huge gamble, much like pre-2011-2012 Hatsans. There was a short period between when Hatsan had to up their springer game to keep selling airguns to Western markets, to when they went PCP big time, that their springers were made well enough consistently enough, that many seasoned veterans spoke highly of them.
Carter, Do you happen to have the manufacturing date of your H125? Hatsan serial numbers are really helpful here: the first four digits. Even new guns are sometimes pretty old when they are bought. In my arsenal, up to two years older than the buy date.
