Be careful of the Davidson -75SA.
I had my LGS go after one for me in January, but the Davidson's picture didn't look right online (curved trigger).
Davidson rep went and pulled one of the 10 and confirmed that it had a curved trigger.
If I'd only realized it at the time, I might have bought it, a -75SA with a curved trigger(!) but we couldn't get the guy back on the phone to confirm that it WASN'T a -75B/BD/Omega that had been loaded into the system incorrectly.
