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

This is my second one. I was so impressed with the first one, I ordered a stainless one for my most recent acquisition!

I was Wrong
I initially purchased a Wilson Combat Bulletproof Magwell thinking there couldn't be a better option on the market. As soon as I saw the photos of the Stan Chen Magwell, I knew I was wrong. The design and the fit is superior in everyway and the finish is just as good for a much nicer price. These are the best 1911 magwells.

Stan Chen SI Magwell
This is absolutely a high-quality precision made product. Directions were very clear, took me about 15 minutes to install, fits like a glove. Add zero width to the frame, and very little extra length. You actually have to be looking for it to see it, but it creates a huge funnel to make a rapid magazine, insertions easy and fumble free. Absolutely would buy this product again.

SI Magwell in stainless steel
I dropped this magwell into a Kimber Custom II 9mm that was given to me by a friend. It slid into place perfectly with no movement and absolutely perfect alignment and blending. The checkering is second to none and the McCormick magazines I use practically jump into the pistol. This magwell is a perfect example of attention to detail and pride in craftsmanship. I will not buy any other magwell at any price.

Installed smoothly without any alteration/fitting into my Springfield Garrison. An excellent product with flawless finish. Couldn’t be happier that I chose this magwell over other options.

Chen SI Magwell - Stainless Gov/Commander
I love the SI Magwell, hands down the best user installable magwell on the market. These magwells fit the factory contours of Dan Wesson 1911s extremely well. Installed two of these SI Magwells on my Dan Wesson Pointman's, add some G10 stocks and you've got a winning combination!
