I installed a race hammer along with a bunch of other work on my p07 and it was a game changer for that trigger. The only thing I had to do was change out the spring in the sear for a slightly heavier one. Easy breezy.
I have been resisting playing with my Steel CZ compact which has a pretty nice trigger from the factory but am seriously considering some springs and a race hammer since it was so very awesome in my p07. Is it as simple a drop in installation as it was on my p07 or is there a great deal more work and expense to installing one on the Compact?
