I think of the cz trigger as having three qualities, grittiness, staginess, and creep, and all are variable from gun to gun.
The grittiness(roughness in the finishing) goes away quickly with clean, lube, shoot, repeat.
The staginess can be caused by tool marks that may smooth out in 5,000 rounds, or not. This seems to be the most hit and miss with CZ?s in my experience, most being better with a few lemons thrown in there to keep you on your toes.
The creep though is inherent to the design and never really changes over time. I have had triggers really smooth out, but the sear engagement rarely changes much, especially with such low round counts. And yes, when they smooth out, you don?t really notice the creep without deliberately looking for it.
Glad you got a good one!
