Simple installation by shooters - No gunsmithing needed!

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

    Magwell added a nice touch to my 1911. Craftsmanship is flawless and fit is perfectly with just a little blending, my mags slide right in without any problems. Definitely worth every penny

    SI Magwell - Stainless Steel

    Posted by Steve A. on 5th Apr 2024

    Purchased a new Bul Armory Commander chambered in 9mm & I knew this Magwell was the one the first time I saw it. I have to say Stan and crew do a fantastic job in all parts of their business, from product manufacturing to communication, fast shipping, excellent customer service & education/instruction! I am absolutely stoked with the Magwell. It really looks like it came with my Commander from the factory. Well done Stan! And Thank YOU!

    SI Magwell

    Posted by Jason I. on 2nd Apr 2024

    I received the SI Magwell very quickly. Upon receiving it and opening the box I could tell right away that this was an item of quality. Mr. Chen's reputation as a manufacturer of high quality parts did not disappoint. The video for installation came in handy and it was easy to follow to get my magwell installed. As an owner of a pre-2018 Colt 1911, I was hoping to have seen a little blending though. Nonetheless, I did the best I could do and I think it turned out good. The magazines don't catch on any edges, so that's a good thing. Overall, I would highly recommend this product to anyone wanting to do some 1911 enhancements on their own. It feels pretty good! Thank you Mr. Chen and crew!

    Oh my gosh my Springfield armory garrison looks like a moded trp especially with the gray and black Lok grips but the magwell tops it off sooooo good my reloads are much faster also. Excellent product, I'm definitely buying more of them as I am a die hard fan of the 1911 Stan my man you out dud yourself.
