It easy to adjust the trigger on the 550 to a nice crisp,no creep trigger.
AND still keep the set function?
Yes
IME, the best, cleanest breaking trigger with the OEM CZ trigger is when the trigger is adjusted to eliminate the single set feature.
You can slick up the trigger and keep the single set feature, but it's hard to not feel a bit of movement. To me that approach is not as clean breaking as the above.
And, be careful with those MIM parts. They can break.
Timney doesn't use MIM, uses real steel (aluminum housing is some models).
Ya gotta like that single set feature a bunch to stay with the OEM CZ.
I don't like that forward positioned trigger, the Timney is back where it should be, as is the AHR.
IMO, YMMV....
