SA Omega and linkless design is great - but - has some potentially serious flaws - and there's no spare parts supply that I know of.
NOTE: If you shoot a SA Omega/Linkless often, the Recoil Spring Guide will crack, either on the top or bottom, right where the hole is drilled for the slide stop to go through. My buddies SA Omega 5" was immobilized by this - and both Peter Stahl and SA didn't have spare parts. The gun was returned to SA for a straight exchange for a .45 Stainless Trophy Match .45
Also, not all SA Omega's had dual extractors - some had a large allen screw that screwed through the left hand side of the frame.
The purpose of the allen screw was to allow easy caliber changes. When the barrel/caliber was exchanged, you screwed the allen screw in or out to push the case rim of the cartridge against a single extractor on the ejection port side.
NOTE: SA Omega's with the allen screw arrangement on the slide have the propensity to crack from the top of the screw towards the ejection cut out. My 6" Target Grade SA Omega suffered from this - and SA gave me a M1A Loadad w/ Walnut Stock.

To preserve one of these things-I think it is a must to get an extra gude rod for the linkless design from Stahl
