SAM used to supply the 1911s for Charles Daly.
There were concerns about fit and durability.
I had one. Every aftermarket part I tried to put on needed extensive work to fit.
Even the grip screws were not standard.
I do not know how their quality is now, but a couple of years ago, I would say stay away.
