This is a tough one. Both are great pistols. The Ruger is actually high at $800 unless it's the new Commander version which is fetching premium prices right now. If it's a Goverment sized SR1911, $800 is too high. I'm not up on S&W 1911 model numbers, but doesn't DK refer to a Doug Koenig model? If it is, it has some extra touches done by S&W's custom shop but the price seems too low for that. I have experience with the 1911 Sc Commander length my shooting partner used to own. It was a fantastic 1911 and that Scandium frame is just a hair heavier than aluminum and closer to titanium in strength. Good luck with your choice.
