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

Perfect
Installed this on a Colt Gold Cup, no fitting required. The fit is as perfect as you can get. Looks great and does not add much length to the grip.

My go-to magwell
I've given up messing with other magwells. The Stan Chen SI fits so well and is so well made, there's no need for others.

The Shooter Installed magwell is a beautiful quality piece. The design and attention to detail by Mr. Chen is obvious once you receive this part. I am extremely pleased with my purchase.

SI Magwell
Finally a company that gets it. Best magwell of all time. Now you can get a magwell that doesn’t restrict the opening in the gun or having to spend extra money in custom gunsmithing an finish work. Absolutely drop in perfect. The only thing is the front two points stick out a hair on my Dan Wesson Specialist.
