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

Great product. Wish there were more finish options
It would be great if DLC and cerakote options were added to the finishes. Quality is top notch.

SI Magwell
The SI magwell went onto my new production Colt Competition perfectly. I followed the YouTube install video, which was really effective. No fitting required, no gap between the bottom of the grip and the magwell, and it mated perfectly with the internal flare of the grip. What an awesome upgrade to the look, feel, and function of the pistol.

Magwell
I heard of the Chen Custom mag well on a 1911 forum and everyone was raving about them so i ordered one for my Springfield EMP and it is incredible. I have others that are two pieces which are okay but the Chen Custom is in another league. The fit and finish are second to none. I was so happy with the one for my EMP That I ordered another for my Colt combat elite. The fit is perfection neither one required any fitting…truly a drop in part for both brands. The next time I need a magwell it will be a Chen Custom.

Without a doubt the nicest magwell I’ve used. Put it on a Colt commander. Minimal blending. Looks like it came from the factory it matches color tone so well. A piece of functional art!!
