Keep them, or swap it out for steel? I don't trust plastic in my beautiful blued steel and walnut pistol.

I say swap. They work but they're ugly.

They are sturdy, self lubricating, and Lightweight.
Metal is nicer.

They're made of Delrin, it's very hard and durable stuff.
The ongoing racial innuendos are not going unnoticed - beware.

Seems like an excuse to get a Stan Chen or equivalent MSH.

Plastic doesn’t belong on 1911s

I switched out the plastic unit for a Les Bear unit l picked up cheap and used in EE.  

Then switched that for a Stan Chen unit. Amazingly both were drop in without any fitting whatsoever.

Bleh looking but they don't break.
Liberals are a curious mix of communism and fascism, they want to destroy you but want to use your own money to do it.

I swapped out the plastic one in mine, tossed it in the box.

Other companies used plastic MSH's and some were known for splitting down the middle.
Colt housings never broke.

There were a few match shooters who installed Colt plastic housings because they were light weight and self lubricating.

Swap for a Stan Chen funnel

You already answered your own question in the last sentence. You will not be happy until it is swapped.

You can't go into battle with that plastic piece!

And It won't, I started this thread and then within a week picked up a Wilson MSH on the EE. And changed out the very nice, but blue Colt grips for a pair of checked Coco bolo grips.

If you don't trust polymer, then go ahead and change it. Your confidence in your firearm is what matters most.

I had the same take when I had a series 80 and changed out the MSH for a steel one. The polymer one never gave me problems and required less care. Since then, my trust in polymer parts has changed. If I had to do it again with what I know now, I'd have left it be. YMMV.

I've had several over the years. Usually put them in a lightweight commander type 1911. Knocks down the weight a bit more, and it is noticeable.

Mechanically they’re fine, but they’re slippery.  I always swapped wm out for something checkered .

I checkered a few plastic Colt housings for people.
I suggested replacing them but for various reasons they wanted to keep the factory part.

I replaced mine with a Stan Chen magwell, largely because I prefer checkered to serrated.

I had one of them, it worked well but I eventually replaced it with a checkered metal MSH.

Personal preference: metal
Practical: "plastic" is fine

I replaced mine with a Wilson Combat with magwell.
Be the change you want in this world.

I replaced mine with a Wilson stainless checkered part.  Not a magwell guy.

I put one on my 9X21 Para years ago to cut down weight. It's done well for 30 years.

They grew on me, I keep them in.  Plastic and MIM get a bad rap JUST because they're not steel, but you'd be hard pressed to find someone in person, that had failure with either in a firearm

MIM absolutely doesn't belong in some parts use but in other parts, it's fine if done right. MIM and extractors in 1911s are an absolute fail. Period. Wrong process and steel for a part that needs to be tensioned.

I leave the plastic MSH alone on lightweights and 9mm. Anything else I swap with a steel EGW MSH.

I got an Ed Brown arched housing for my Colt Competition.45, steel, just because I prefer steel and arched

I replaced the nylon  mainspring housing with a steel blued arched serrated mainspring housing with a lanyard loop from EGW.
