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.

First Class part
The magwell shipped quickly is is very well made - first class materials and first class workmanship. It fits my Dan Wesson Valor very well but, of course, is not perfectly blended. It is however, very attractive and more than functional.

Top Notch
Fast shipping for this phenomenal magwell. Beautifully machined and dropped right into my Fosters frame with no gaps and no fitting required. I will definitely order more for future builds.

Kimber perfect fit
The SI magwells are a perfect match for my Kimber 1911's .So good that I am not going to even bother with the very minor blending that could be done. On my Springfield Armory 1911 loaded there was a small gap between the bottom of the frame and magwell. I will be recommending the SI magwells to others.

Great Looking Magwell
I installed the magwell on my Dan Wesson Valor 5". I had some questions about the installation and the customer service I received from Stan Chen was superb. The magwell looks and functions as well as my hand blended full customs.

SI Magwells: It’s beautiful,man!
I bought these to install on my SA TRP Full Rail and Colt 1991A1. Fit beautifully on both and surprisingly my TRP need minor blending. I am impressed beyond words: bought 2 more to install on a fellow Marines 1911s. Will report those on a separate review. For what I paid, I stole these SI Magwells. Thank you Stan Chen Custom!

SI magwell
The machining and finish is absolutely first class. Beautiful craftsmanship. This is for a future project, so I don't know if this will drop right in or need some minor fitting. Either way it's a beautiful piece of workmanship.

What a superior product!
My SI magwell arrived a day early and I had no trouble installing it on my S&W 1911. The stainless matches perfectly and looks great. Thanks for such quality and attention. The M&Ms were also tasty.
