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

Shooter Installed Magwell - Springfield 9mm - 1911
Excellent service. The shooter installed magwell was installed on a Springfield 5" - 9mm (P19134LCA) and the fit and finish was excellent. Not only does Stan Chen produce an excellent product, but his personal message was heart felt with concern if we had been impacted by the fires in northern California. It is a pleasure do business with Stan Chen Customer.

Best 1911 Magwell on the Market
I ordered two of SI magwells after seeing them on the 1911 Forum. The introductory price was just plain unbelievable, and there was no way I was going to pass this opportunity up, especially knowing these magwells have Stan's name on them. I did expect to have a little fitting work to do, but I was surprised to find out that these magwells dropped right into Kimber steel frames with zero fitting. I would put this order in again in a heartbeat.

PHENOMENAL PRODUCT at a FANTASTIC PRICE
Exactly as advertised! Very high quality product and a simple install with an outstanding end result. The angle of the mag-well blends perfectly with my Kimber, DW, and SA 1911's - Yep I bought 3 a this price...... ;-)
