RIA owners and shooters tend to be pleased with their 1911’s, and I think you will also. Congrats on the purchase my friend, and welcome to the rabbit hole that is the 1911.
My advice, spend time with the gun in stock form to see what you like or don’t like. Time and rounds down range can be helpful in choosing upgrades, if that is applicable. You’ll know after after a few hundred rounds, if not sooner!
Spend some time watching reputable 1911 videos on YouTube (Wilson, 10-8 performance, etc) and learn things like extractor tension. Most suggest changing recoil springs every 3,000 rounds. Make sure you use good mags, and verify function in your pistol with the ammo you use. Not all 1911’s and mags jive. Some do, some don’t it seems like to me.
@JTQ mentioned drop in parts and he is 100% right. Expect to do some fitting here and there to make aftermarket parts work on your pistol. It’s just the way it is on 1911’s.
Lastly, I would say that 1911’s don’t necessarily have to be white glove clean to run, but I do think they work better when wet. Hit those slide rails with lube more than you would on something like a Glock.
There are several here on THR that are a goldmine for 1911 knowledge. JTQ knows some things,

@Skylerbone,
@tark and others.
Whenever those guys start talking, I generally just pull up a seat and start listening!
