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
Excellent quality and tight fit. With out physical blending the transition is quite good, the Magwell works great on my Dan Wesson Valor and makes for a much cleaner and faster mag change, thanks!

Awesome product
This magwell popped up on google when I searched for best aftermarket magwell and I’m Glad it did. Install was extremely easy and it fits like a glove. It’s like it was made specifically for my gun. Great addition to any 1911. Highly recommended

Nice upgrade to my Ruger 1911
Ordered the stainless and installed it on my Ruger Stainless Target II. A perfect fit and did not require any 'fitting'. SC makes a quality product and really make my 1911 look custom. Used the inners from the Ruger's MSH and did the function check, all in all it was a piece of cake! Thanks Stan for a high quality product!

THIS should be your first upgrade
When I got my 1911, over time I upgraded the recoil spring kit, the trigger spring, sear spring and magwell. All in that order. Had I known what I know I would have done the magwell first.
