faello5,
I have a Walther P990 that I just purchased from CDNN. I also have a P99 with the original trigger. If you have handled the original P99, the trigger on the P990 is EXACTLY like the double action pull on the original P99. If you've never handled the original P99, I can only compare the P990 trigger pull to a revolver in double action mode.
I was not really sure what to expect when I ordered the P990, but I am happy with my purchase. The day I received it, I did'nt think that I would be able to shoot well with it at all. But to my delight, I surprised myself when I took it to the range last week and shot really well with it. I fired 100 rds 115 gr American Eagle and 50 rds 115gr Georgia Arms Gold Dot ammo without a hitch, the pistol functioned flawlessly. My only complaint is that after about 100 rounds, my trigger finger was getting alittle raw from pulling the DAO trigger! But I was getting good tight shot groups with it. For the $399 that I paid for it, I'm pleased. Are you thinking about buying one from CDNN too? They are a good company to deal with if you are, very quick delivery. E-mail me if you have any more questions.
Mike
