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.

Chen SI Magwell
Absolutely fantastic and dropped in perfectly on my 9mm Springfield Garrison with no fitting at all. The rounded rear cut on the magwell took away the sharp factory edge on the mainspring housing and reloading is now a breeze. Any 1911 I get in the future will 100% be getting a Stan Chen magwell.

Chen SI Stainless Magwell
Wanted a Magwell for a NH Classic I picked up. Was expecting some difficulties with the round butt frame of the NH. The SI Magwell went right on like it was made for it.

I installed this on my Springfield Vickers Master class! Looks gorgeous and function incredible. Very pleased fit and finish is what you would expect with a high end Chen part. Not disappointed would 100% recommend. It’s expensive but you get what you pay for!

Well made solid construction. Went in relatively easy. Adds to the great looks of a Kimber not to mention functionality.
