Looks good and works, but might need a little filing - Fusion Firearms 1911 Mag-well Mainspring Housing

I bought this Mag-Well Mainspring Housing for my RIA 45 EFS. I thought it would be a simple drop-in upgrade with no trouble, for the most part, it was, but there was some filing that needed to be done on my part to make the part fit. It was not an issue for me to do, but I would suggest to those who are going to buy this item, that they have a mini file handy to make some adjustments to the tab that connects the Magwell extension to the mainspring housing. Overall I am happy with the product
