When I got my first 92, the blued braztech SRC, i replaced the springs with the steves gunz kit and filled it with regular old white colgate toothpaste and worked the action while watching tv for about an hour. It's smooth as silk now. My stainless interarms "pre safety" 92 SRC got the same treatment but it was already pretty smooth after the springs were replaced. it too is smooth as silk, if not more so than the blued rifle...
On another note, i like the saddle ring carbine the best. the saddle ring attachment loop gets the rifle up off the table a little bit and makes it easier to pick up in a SASS match...
