After giving it a good cleaning, replacing stock parts with CGW #18 spring, firing pin spring, reduced power trigger return spring and the firing pin retaining pin took it for some bang bang.
About 450 rounds shot. Federal and federal alu, Tula, Federal HST 124 and Hornady Critical Duty. Not a single issue. This thing is absolutely amazing.
First 50-60 rounds I though that the sights might be off cause I was shooting slightly to the left but one of the instructors on site told me just to keep going if this is my first hammer fired gun.
In the end I was able to shot consecutive headshots at 25 yards.
I got few thumbs up as apparently not many people have seen then version with threaded barrel and I also got one guy telling me how 9 is inferior and that I have a tacticool target plinker

Since everything is running smooth I'm gonna install the comp and head again tomorrow.
On a side note there was a lady next to me shooting her Sig 938. Since I really do not like (that means I have trouble shooting my carry G43 and even after 800 rounds still can't get used to it which means that placing that first shot from draw in the center is not a given thing) my G43 I asked her if I could shoot a few rounds. We swapped guns and oh man that little sig is amazing. Just feels right compared to my glock. Once I finish posting this my G43 is going on sale

.
I shot 18 rounds on that sig while that lady went through entire box of 50 with the P-07 and a big grin on her face

Great day. Love my CZ!
