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

Excellent product
I've installed several SI Magwells on various versions of 1911. They seem to fit very well as I've used more than a dozen and have had very little difficulty installing them.

SI Magwell
I received my SI Magwell on Tuesday and immediately installed it on my Colt Rail Gun. The fit exceeded my expectations and blew away the one I had on. There was no gap between the magwell and the frame, and when my grips were replaced, it looked like it came with the gun. You make an incredible product and the customer service is superb. I can't wait for you to make an ambi safety, because I will buy one. Thank you again!

Great magwell
The SI magwell is a great fit on my 1911. 25lpi matches the front strap checkering. Top notch product as one would expect from Stan Chen!

Sweet looking and functional
The SI Magwell was the icing on cake to an otherwise perfect pistol. The perfect upgrade to my DW Valor, functional and ascetically pleasing. The hand written thank you note and m&m's only amplify the term "Class Act". Thank You for making available such fine postal accessories.

My first purchase and it will NOT be my last.
Easy installation, excellent quality and perfect fit; Stan's magwell has transformed my Springfield 1911 and has helped me noticeably improve the "smoothness" of my reloads ... and his bag of M&Ms in the package was a touch of class. Thank you Stan.

SI magwell
I ordered this magwell from Stan Chen for my carry gun. It's a Springfield Range Officer Compact .45. This magwell went together beautifully, no modifications were necessary to the magwell or frame. This was the easiest magwell I've ever installed and will be ordering again from Stan. Very quality piece, nice checkering and the black finish matches perfectly.
