Hey all I just bought my first pistol. It's a Ruger 9mm, it says P89 on it but is black with a silver slide and all the one's like that I've seen are KP89's. What the difference in these? I also want to see about popular accessories for it like extra mags, laser sights, etc. I'm mainly using it to have fun with. I take it on the trails with me when we go on the 4 wheelers. I think I got a pretty good deal from my neighbor who bought it new and shoot less than 100 rounds through it, and I only gave $250 for it.
