Not to rain on your parade, but I came into this thread expecting to see the actual SOCOM version, not the civilian model. The price difference is a whole lot different if you manage to get your hands on one of those, as they havent been replaced, nor will they anytime soon.
Still a nice looking piece...but a misleading title.
I don't think there is any meaningful difference between the two. Besides, HK refers to the Mark 23 as a SOCOM. Here's a quote about the Mark 23 from the HK website:
"THE ULTIMATE SERVICE GUN OF THE US ARMY SPECIAL OPERATIONS COMMAND. The best equipment for the best units. After the toughest comparative trials of the US Army Special Operations Command, the MARK 23 defeated all competitors. It was adopted under the designation MK 23 MODEL.O US SOCOM."
