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

Chen SI Magwell
I bought two, for a Colt Commander and a Colt Competition, both recent production. I doubt they would have fit better if Mr Chen himself had installed them. Excellent product.

Blue SI Magwell
I've got a safe full of 1911's most running magwells dating back to the 1980's. The Stan Chen magwell is by far the nicest looking, best fitting out of the packaging magwell I've ever used and I used to build 1911's. The fit is so close to the flare in the SA frame its not worth my time blending it and having to clean up any mess I'd make. I'll definitely be recommending your magwells to anyone looking for one. Thanks for a wonderful product. Oh, the M&M's were a nice treat - thanks!

Best magwell ever
This is the best magwell ever. I just installed on one of my my STI 10 mm and it not only improved my ability to fastest reloads, but the appearance of my pistol.

Best magwell!
I have a Les Baer & decided to give the Stan Chen SI magwell a try. There was about .005" interference on the bottom ledge of my frame stopping the MSH pin from going in. I slowly filed a bevel on the frame, MSH/magwell now goes on TIGHT and with ZERO gap below the frame. I expected WAY more work, as Les Baer frames can be non-standard sizes. Couldn't be happier, best magwell for a single stack 1911 PERIOD.
