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.

Thank you, Stan Chen!!!
Stan Chen SI magwell is now considered standard equipment on my 1911’s. The edge to edge ramp design and fit finish are just so much better than other magwells.

SI Magwell
Installed on Colt 1911 Competition; with magwell-specific VZ grips in OEM blue gives a stunningly smooth, clean feel and look. Should have been like this from the factory! But absolutely do wear your safety glasses during installation as the tension in the mainspring could really send some pieces flying if you're not paying attention.

CHEN SI MAGWELL
The CHEN SI MAGWELL fit and finish is second to none. My Springfield Ronin is becoming a real conversation piece.

SI Magwell
First time purchase of one of these. Initial impressions are outstanding, from the machining to the layout of the 25LPI checkering, everything was exceptionally executed. Checked the fit to the frame to be used on the build and it slid right in, snugly without any fuss. Can't wait to put it to work! Nice work Mr. Chen.
