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.

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

    3 Black & 1 SS Chen SI Magwells

    Posted by Everett Michael on Jun 9th 2022

    I bought 2 NH magwells installed them, blended them and hate them. I scoured the WEB looking for something better. I did so many searches that magwell sources started showing up everywhere in went on my devices. Chen caught my eye. Bought 1, loved it...bought 3 more. They all look great. I'll get around to blending them one day but no need to hurry....they're close out of the box. The SS one on my MR-1911 is so close I may never touch it.

    Outstanding 1911 Magwell (3rd purchase)...

    Posted by Gunny M on Jun 2nd 2022

    Simply an outstanding well made one-piece mainspring housing and magwell that installs and functions flawlessly. I have one on a Smith & Wesson, Springfield Armory, and now a Sig Sauer 1911, and they are all running great with no modifications necessary. A highly recommended addition to any full size 1911.

    I would love to give you a review but I haven’t received my order yet. It’s been weeks and still haven’t gotten it. You’re website doesn’t have a contact phone number either.

    I was surprised by the low cost after I received this magwell! Top notch machining. Excellent fit on my Pointman 9. The checkering is first class. What an amazing addition to any 1911…a must have!
