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

    SI magwell

    Fit was superb. Blends nicely with the factory bevel. No modifications were required. Been using Wilson Combat bullet proof one piece magwells a nice product but those overhang the factory bevel and requir blending. This was a nice drop in option. Makes hand feel like it’s locked in on the overall feel of the grip.

    This product is awesome when they ship you a bag of peanuts MM and tell you by the time you finish eating them the magwell will be install. And that was the truth. It's a nice product is worth the money and I will continue doing business with them.

    Bought 1 - then another - and plan another

    Posted by Stephen Dobek on Oct 4th 2022

    Bought one for a customized 2002 Springfield Loaded - had to adjust the pin hole by a MINOR amount. Liked it so much I bought a second one for a 2011 Colt Combat Elite, PERFECT fit with just a little blending. Again, so Happy, I plan on buying another for my EDC Colt Government. Got to meet Stan and kids at IDPA Nationals. Nice Guy.
