After about 400 rounds or so the SAM's smooth out wonderfully. The trigger pad on the Omega might be a little longer but if it is it wouldn't be by much.
The 1911 is one gun in which lefty shooters actually have an advantage.
While most right-handed people have to shift their grip to reach the slide stop or mag catch, left-handed people can simply reach up to the slide stop and down to the magazine catch with the trigger finger.
This not only takes your finger off the trigger, you don't have to shift your grip.
We can also do a layaway for you if you are interested.
