Hi Bill... thanks for the kind words.
It's not exactly a piece-by-piece DIY guide... more a quick overview for folks that are mechanical and already have an ability to take things apart and put them back together without having any parts left on the table.
It takes way longer to disassemble, clean and lube everything than it does to actually do the trigger work... but the benefit is well worth it if you like a smooth, reasonably light, clean breaking pull.
I think as time goes by, more and more people will get Fusions... there are just so many nice features that they're really a good deal in my mind.
Cometa has been in and out of the states, but I think (or hope) that they are here to stay. At the $350'ish price point, they aren't cheap, but they aren't horrifically expensive either. Hell of a gun for the money.
Take care and Merry Christmas Bill,
C
