It's the stainless model, which has been discontinued. They were a bit more expensive than the standard HE finish (Hostile Environment, HK's equvalent to Glock's Tennifer).
The 8 rounds is the standard for the compact, not a ban thing, a fat bullet thing.
The safety can be changed to the right side for left handed use, or removed completely if you want a double action only pistol. The safety/decocking lever can be set up in a number of ways, safety and decocker, decocker only, or safety only double action, or safety only single action, now add the left handed versions of those and you have 8 options, Plus the no safey, no decocker and it's up to 9. It just takes a person who knows how about 30 seconds to make it left handed. Just a new lever (so the letters aren't backwards) and the detent plate inside which actually determines which varient it is.
