I have waited for so long! I have wanted the SP89 for as long as I can remember and it was always just out of reach. I bought an 89K/40 from Vector several years ago and when ATI was importing the MKE's I got the AT94=K. While I like them both, I really wanted to have the real deal as part of my collection. I was really excited when I found out that the SP5K was going to be a reality. I am so happy that it was in reach and I was in the position to get one. When I got it, I wasn't happy with the short selector lever on the left side. It worked fine, but my 89K/40 has the extended version and I like it better. I got the C and P Pictogram lower and the extended selector from HKParts.net and couldn't be happier. They both fit perfectly with no mods required.
If you are on the fence thinking about getting this weapon, don't wait, get one if you can. You will love it!
