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

    Drop In Magwell

    Posted by Custom Arms on Dec 7th 2021

    Stan, Your drop in magwell blends nicely with Custom Arms frames! Leaves me with minimal work to create a nicely blended mag chute, and looks great too. Also the MSH portion fits nicely in Custom Arms frames with virtually no filing or sanding. I will send a few pics soon. Quality matters!

    I purchased a Stan Chen SI Magwell for my Dan Wesson Commander Valor in .45 ACP. It is an excellent quality product. The install was easy just as stated in the item description. I would highly recommend this product and other Chen items to anyone looking to spruce up their 1911. I am very happy with this purchase!
