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

    Perfect !!!

    Posted by JOEY on Dec 4th 2021

    The best magwell. I have a few other brands of magwell, but this one by far is the best. Perfect fit…no “minor fitting required” like my other ones. Stan and Libby were very helpful. I had a malfunction with my device when placing an order and made three orders by mistake! Libby caught that (very smart and honest), and confirmed with me first and surely saved me some headaches in the process. Also, I wasn’t sure if I ordered the right one, so Stan made sure I was taken care of. Very nice and most pleasant experience! Outstanding and very professional. Thank you very much SCC and more power to you! Highly recommended !

    SI Magwell

    Purchased one of these for a pre-2018 Colt Competition model. As expected, some frame blending was required but the fit-up of this magwell was flawless. No gapping anywhere and the overall look and feel is excellent. If you're considering trying one of these, you can't go wrong. I had a few questions for Stan before I purchased and he was very quick in his response to my query.

    Haven't got it yet so I can't give you a review on only putting one star because I haven't seen it or installed it.
