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

SI Magwell
I purchased the SI Magwell after asking a few questions (which were promptly answered) and could not be more satisfied. The Youtube video on the installation was professionally done and easy to follow. Fit and finish are of the highest quality. A fantastic product!

Excellent mag well
I have to give Stan props for the install video. Really well done and easy to follow. At one point I was contemplating which direction the safety spring went in. Stan stops at that point in the video and clearly states "the smaller end goes in first". Ah, thank you. Easy install, finish looks great, matches up perfectly with my Springfield Range Officer Elite Operators, and works flawlessly.

The Best There is!
This is my third SI magwell. It is amazing how well they are constructed and have fit 3 different 1911's perfectly. Special thanks as this order (and others) were misplaced by FedEx. Libby did everything in her power to resove the issue and kept all customers updated on the progress. Even FedEx apologized. Product and service simply can't get any better than this. Thank you!!!

Recent order
Perhaps I should wait until I actually receive the order to review it. I realize that this problem is caused by the FedEx delivery backup. I will be happy to send another review when I received the order and use the products. Thank you.
