I definitely second this. I had David @ CGW upgrade and tune my steel-framed CZs back when that was what I shot because I didn’t feel like I’d do well reassembling the (somewhat intimidating) sear cage but the polymer Omega system guns are much more straightforward to work on. The sticky points for me were: 1. The decocker spring - after wrestling with various approaches, I now put the spring leg in place using a locking hemostat. Still takes me a couple or three tries but that is better by far than my previous records LOL 2. The trigger return spring - a slave pin really helps out with the trigger reassembly. I used a spare hammer pin but a bit of a Qtip or toothpick will also work. HTH [emoji4]
