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.

SI magwells
I have have purchased and installed three of these. Two on Dan Wessons and one on Colt. They all fit very well. Will be ordering more. Make a very good looking firearm with the magwell grips.

Superlative!
From design to production quality to fit and finish this magwell is absolutely impeccable. It installed with no fitting necessary, and looks like it was custom blended to my gun. Customer service is fast and friendly too. I will be ordering more for all my 1911s

SI Magwell
Quality Product when I opened the package. Took about a half hour to install. Would rate it after the install 99 0ut of 100. Does not line up all the way on the sides on the magwell along the frame. You have to be "looking" it and it might be the frame and not the magwell. That being said. Would still absolutely recommend this product.

The proper upgrade
I installed two SI Magwells. One a kimber and one on a springfield. The fit and finish and ease of installation, make for a much needed upgrade. I would recommend this to anyone. The craftmanship bespeaks to the old ways, when a pistol was built by professionals. Stan is one of these gunsmiths. Thank you for your attention to detail...and the M and M's
