Hello everyone!! Hopefully I have not buggered anything up, however in picking the colors. I wanted the red on the inside, or closest to the body, with the black being outside. I am guessing that is what you meant by inside and outside, however I just wanted to be sure. I wasn't sure about the sights, I think the Staccato comes from the factory with the taller sights, so I picked it. I also got the threaded option as I ordered an additional barrel with mine. I have also ordered the TLR7sub/1913 model, and I believe from the website that they are using key number 4, so that is what I chose(if that is wrong, please let me know). If I have messed anything up, please feel free to give me a call at 602-710-5681. Thank you, and I hope you have a wonderful day! David Silverstone
