Reviews & Ratings for Evolution Gun Works 1911 Premium Mainspring Housing/Magwell Combo — 6 reviews — Page 1

Two parts were packaged together with no padding so the well damaged the texture on the housing. When I went to install it the part was so poorly machined that it took significant effort to remove enough material for it to slide into place. On one side you could visibly see how the tool had drifted when cutting and it was curved. This part should never have passed inspection. Pretty disappointing. The idea seems good but it wasn't well made or packed correctly.

Very good fit and finish! Fit my 1911 perfectly no play in the components!

This part has the affordability of a 2-piece magwell/MGW but with none of the downsides. I have an Ed Brown 2 piece magwell that loosens under recoil even with using loctite on the screw connecting the two parts. This EGW part uses an attachment mechanism that fits tightly but has no way to come loose when installed in the gun. No reason to get a more expensive 1-piece magwell/MSH when this part exists.

Picked this up to add to a 10mm 1911. Typical disassembly process. While I had it apart I tuned the trigger a tiny bit, but thats not the point of this review. The magwell mainspring housing is a great design, with excellent fit and finish. I am very pleased. It matches the black hardware on my pistol nicely (your mileage may vary) and looks factory with the added magwell grips I picked up. Installation was easy and straight forward. Swapping over the mainspring and pins was textbook easy, and the entire install.kight have taken 15min, from knocking the MSH pin out of the frame to start, to knocking it back in and testing the trigger and safety function. The magwell is tight and unobtrusive so it won't interfere with carry if this is your preferred carry pistol, either.

Ordered this as part of an ongoing project to improve and dress up my RIA 1911 a bit. Install was straight forward, after pulling the RIA MSH out of the gun during a full detail strip. I swapped the internals over from the old MSH (which turns out was a very well done checkered flat metal housing, not the plastic I'd anticipated when I bought the gun, based on internet forums) with zero issues aside from the usual pain in the neck in getting the MSH retainer pin in place. Installed the new magwell MSH on the pistol and it looks great! Fit is nice and tight, but not overly so. Magwell sits nearly flush to the base of the frame - have to hold it just right to see a sliver of light protruding. I could probably adjust the magwell arms a bit but it's not noticeable so I'll leave it alone. Inside the magwell, the arms align to the frame (which was already slightly beveled internally) very well, so no fitting or smoothing was required. Overall, This piece is great, and the black color matches the RIA factory black accessory color on the beavertail grip safety, hammer, thumb safety, and slide release, so it looks like it came from the factory with this magwell MSH. I highly recommend it if you're looking for a simple, secure, quality upgrade. I considered the Ed Brown part with the cap screw holding the magwell arms to the MSH, but decided I thought this one had zero chance of shaking loose with it's tongue-in-groove style fitment. That was a little fiddly to get perfectly...
