I just acquired a new Sig 1911 Carry in stainless. It is not as smooth as my STI, the trigger isn't as silky as my STI and I prefer different grips than the stock.
However, words of wisdom from Canebrake: shoot it, clean it & repeat (summarized quote). I changed the grip only because it suits my hand (and looks better
). Beyond that I'm just going to shoot the snot out of it.
Personally, I won't CC a pistol until I have a minimum of 500 rounds through it because trust must be earned, especially by something that I carry to prevent me or mine from being hurt/killed.
After you have at least 500 round downrange, then think about making functional changes. JMHO
