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

Best MS housing/Magwell ever
I’ve used most of the competing brand units like this on the market. The Chen unit is by far the best I’ve seen. It fits properly with factory beveled magazine wells on today’s popular 1911s, whereas everyone else’s models are still made to fit old style unbeveled versions. So they need to have a lot of metal files away and blended to make a decent looking installation.

Thank you Stan! Excellent product. Perfect fit. When my wife saw the M&Ms and the personal note on my invoice she said “now that’s customer service and a company you want to do business with. Keep up the good work thanks

Perfect !
Bought two of these to replace the older style, blocky MSH/Magwells on my DW Kroll Edition Valor and DW Specialist. Perfect fit and perfectly undetectable color match DW Black Duty Finish !

Magwell for Bul Armory 1911 Government model
The magwell is more than I had expected, an excellent piece of engineering. Installation was very easy, as I followed the instruction video on Stan's website. I would highly recommend to anyone looking to purchase a magwell that want to install it themselves. I will definitely be a return customer.

Excellent Product !
Easily installed and feels great. Even though my mag opening was not beveled & expected to have to do some blending, this was not the case. Mags slide in easily. Thanks Stan !

Great Service
Ordered a shooter installed magwell, and had it two days later, with a bag of peanut M&M's to boot. I have found their magwells to fit best with all my 1911's
