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.

Shooter installed magwell
Easy as the instructions show how to install. Would be nice to have the purchase option to already have the spring and pin installed so that it truly is a plug and play improvement. I get it is simple enough to do it yourself. But it would be nice to just take the part of the package and simply slide it on the gun. Other than that quality piece and quick turnaround time.

Fit my trp operator full rail beautifully! Nicest 1911 Magwell on the market. As nice or nicer than the other big name Magwell manufacturers out there.

Fantastic product. Dropped into a Series 80 Combat Commander with 3 file strokes. Fit & finish is outstanding, nearly a seamless fit inside of the magwell.

By far, the best fitting and highest quality stainless I've ever seen in a magwell. I've used several different brand names. This a winner. Will be getting another one for my black 1911 too!
