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...

Installing this magwell will require much fitting.
Definitely not drop in. Gaps at the well. MSH negated my grip safety. Will need much filing to fit correctly.
Would recommend spending the extra money on a Nighthawk.

I was looking to install a magwell to my Kimber CDP, mainly for the reason to get more comfort out of the grip. As it would dig into the palm of my hand. NOT ENYMORE! this magwell is SOLID. the backstrap and magwell itself is actually a 2pcs part, both come together with an hex head small bolt. No issues installing it. It slid right in and made sure to use some blue loctite on that bolt/screw. I've had no issues since I installed it and have been carrying it for the past 2 weeks.
Pros:
Solid and Fits Perfect
Cons:
2 piece design
Best Used for:
Officer size 1911's
Would recommend: Yes

Solid piece! Fits really good and gives the pistol a much better look and feel. Before the magwell the coner of the frame would dig into my palm. Now with the rounded contour of the magwell, it's much more comfortable.
Pros:
Fits very well
Cons:
It's a 2 pcs magwell
Would recommend: Yes

I bought the stainless version of this for a Ruger 1911. It fits easily, color match is good with the Ruger as it has a light bead blasted finish. Bevel is good for faster insertion. Price was on good as it was on sale. No complaints.
Pros:
Drop in fit
Cons:
None
Best Used for:
Improving reload speed, good for concealed carry or competition.
Would recommend: Yes
