Replace original hammer spring with a #16 lb. hammer spring.
The CGW Reach Reduction Kit is a good option, especially with
the trigger adjustment screws. I did find that the trigger
included with this kit had "sharp" edges. Not enough to cut,
but in my case, enough to annoy - especially when it's cold
and my hands are all dried out.
I took a cratex bullet nose polisher and worked on the offending
edge [by hand] - not with the dremel. This preventing me from
creating any unwanted spots on the gun's finish. It took maybe
fifteen minutes, but now it feels very nice.
You can't go wrong with the Reach Reduction Kit. Just take your time.
Good luck with your CZ journey.
