The trigger on my 455 is tolerable, as is. No need for a kit, on my rifle, anyhow. Mine shoots so-so in .22LR, but shoots pretty darned good as an HMR. I might fool around and get a WMR barrel for it sometime this fall, if I can force myself to do so. (I have a Hornet, so it would be pretty redundant, in my case). I like the rifle, but switching barrels requires a massive re-zero, like 12" at 50 yds. massive. It's sort of a sore point in the otherwise good experience.
