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.

Awesome
Luke many other reviewers, I decided to add a magwell to my 1911 and chose the Chen SI. Wow! I was not disappointed, easy evening project to transform my SA Loaded 45. Great product, delivery, service. Thank you.

I own a couple of different magwells. I have a Wilson combat and an Ed Brown , both are mainspring housing magwells. The SI from Chen customs is heads above them both. The fit and finish are gorgeous. The color on stainless is darker than I hoped. It fits great, no blending was required. I am throughly impressed with the craftsmanship. If the color was a better match you would swear my 1911 came with it from the manufacturer. Don't second guess it. If you need a mainspring magwell this is the one for you.

Went together easily and looks amazing. Will be adding the beavertail safety to the pistol soon. Definitely worth the buy.

Fit and finish matches perfectly with my Springfield Champion Operator. Love the checkering. The install video was perfect. This is my first time getting somewhat deep into the disassembly of a 1911 and Stan explained the process perfectly.
