I had one and it was a good pistol. They are on sale down here in Evansville at Rural King for $379 and I think that is a hell of a deal. I shot mine ok when I had it. I would buy the 3.3 if I was going to carry it daily. I know this was not all of the info you are looking for but I hope it helps.
I have had great luck with my wasr's. Then I went over to atlantic firearms and bought the russian red stock set for them and it turns them into a thing of beauty.
I have an FN Scar 16s in dark earth. Just kicking around possibly selling it. I have no clue what the market is on them. Guessing around 700 rounds thru it. Where do you go to look at the value of a used gun?
