As an owner of three Tisas 1911s, I agree with these guys, though this should go for any new 1911. Any new gun actually.
At bare minimum, put a few boxes of different factory ammo through it before changing anything. Especially if this is your first 1911. The 1911 is not a Glock or an M&P. or an AR. It's a lot easier to jack something up.
Chances are it will run like it is and once you get a feel for it, then maybe some upgrades will make more sense.
OR...
... you can do whatever you want, because it's yours.
