It's hard to tell without looking at the pistol and you, while you're shooting it. Some folks can confuse trigger technique issues with sight adjustment issues, and then when it comes to 1911's the length of the triggers can affect some folks, too.
I also happen to prefer the flat mainspring housings.
I can say that the new stainless Colt Government XSE I bought was a tack driver right out of the box, without any adjustment of the factory sights.
The new SW1911Sc I just bought had a front sight which appeared slightly off center in its dovetail. The rear sight base was perfectly centered. I like to start with dovetailed sights both centered when first trying a new pistol out on the range, so I used a sight pusher to center the front sight and took it off to the range ...
That SW1911Sc is a REAL tack driver. It pleasantly surprised me. I let another one of the instructors shoot a box of standard W-W 230gr JHP's through it, and his unsolicited response was that it was a REAL tack driver. Funny. He carries an issued Colt 1911, too, since he's a 'special' fellow.
You'll have to decide if the stock trigger just doesn't fit your hand size. There's a decent medium length trigger available on the market which some folks like, too. I have one out in the bench, given to me by another armorer who highly recommended it, but I haven't had the time (or inclination) to replace either of the stock triggers in the XSE or the Sc yet. Maybe later.
Whenever there's a question of needing to adjust sights for windage, I generally make sure they're centered to start with (some folks forget to check the front sight if it's a dovetail), make sure the shooter's trigger technique isn't affecting things ... and then take it from there.
I have a Ruger P-90DC that actually required the rear sight base be adjusted almost all the way over to the right ... regardless of how carefully I shot it, what ammunition was used, or how I held my mouth.
