I got my s9-a1 last week and had a post asking about the advice on the tight extractor. Then I went to the range last weekend to try it first time. It is OUTSTANDING . I shot 100 rounds totally, some WWB, some PMC. Both worked excellent, no FTF, no FTE, no brass on head. Nothing. The trigger pull felt SWEET, very short travel and solid but crisp break. Very satisfied. Accuracy was not bad either, just need some time to get used to the sight. What a nice gun!
