Simple installation by shooters - No gunsmithing needed!

The SI Magwell is the latest addition to the Stan Chen Custom Magwell family. It delivers greatly enhanced reloads, elegant design and maximum durability.

Solid, one piece construction.
 
FEATURES

Large sculpted funnel for dramatically faster reloads. Through careful CAD design, every last millimeter of available real estate was turned into reload-enhancing surface area.


Designed to very nicely match the beveled magazine wells commonly found on current production 1911s, such as Springfields, Kimbers, Dan Wessons and current Colts (2018 production with fully beveled magazine well) .

Most Colts made prior to 2018, and other frames without full magazine bevels, will require minor blending. (See pictures above). We offer a "Blend Kit" to facilitate this (located under "Accesories").

 

Eliminates sharp frame corners. Unique funnel profile eliminates sharp edges at front of magazine well opening on the frame. Smoothing of all surfaces on the entire part yields total carry comfort.

Low profile roundbutt. Flowing design. The lines of the entire magwell were designed to flow well with the pistol, giving the bottom of the pistol a cohesive, custom look.

 

Custom quality checkering. Equaled only by the very best gunsmiths. Perfectly formed diamonds, row after row. Even at 20x magnification. Enhances recoil control.

One-Piece Durability. Precision CNC machined from a solid block of heat treated steel. No joints or screws to work loose, ever.

Made in-house at Stan Chen Custom, Durango, CO, USA

    Stainless Magwell

    Posted by Brian on 20th Nov 2025

    A perfect match for my Springfield 1911 Loaded. Color, fit, and finish is perfect. A must have upgrade for any 1911. Thank you Steven!

    Shooter Installed Magwell

    Posted by Tom on 20th Nov 2025

    Looks great, put this on my Bul Armory Government 1911. Had to fit the bottom edges a little they were a little pointy and stuck out a bit. Nothing major that a little filing with a jewelers file didn’t handle. You don’t have to do that but I am a little picky. Overall, fantastic workmanship stainless steel matches the rest of the gun looks a million times better than the aluminum MSH originally on the gun. I highly recommend this product.

    Great Magwell

    Posted by J Becker on 11th Aug 2025

    Excellent product! I have it installed on three of my 1911s - a Wilson Combat CQB and two Kimbers. Great fit and works fantastic in competition (USPSA Single Stack and Limited 10).

    SI Magwell, Blued

    Posted by Tom W on 2nd Aug 2025

    Easiest part installed onto my operator yet, excellent quality and makes a huge difference in feel to the pistol; as well as, reloads. 10/10 will always recommend this part to anyone. Badass product, gents.

    The magwell is a work of art!! Installed effortlessly in my Colt lightweight commander. Makes reloads a thoughtless process. Fit and finish matches my firearm perfectly!!
