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

Easiest part installed onto my operator yet, excellent quality and makes a huge difference in feel to the pistol; as well as, reloads. 10/10 will always recommend this part to anyone. Badass product, gents.

Chen SI Magwell
I am very pleased with the craftsmanship of this mag well. Fit and finish are amazing! This looks and fits like a hand fitted part and not simply a drop in piece. Installed on a Springfield MC operator in minutes. Top notch sales and service. Thank you again.

User installed 1911 magwell.
The fit was perfect with the grips that was on the f/a. It was a flush mounted grip and I wanted it to fit nice. I was impressed with that fit and was an excellent magwell for fast reloads.

Great product, well made, fits my old Springfield tight and required fitting to the frame.
