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

The best magwell
I have magwells on all my 1911’s , Chen SI magwells are by far the best. I just wish they would come out with one for the 4” EMP

SI magwell
SI Maxwell was outstanding in every way. It had a snug but perfect fit into my 1911. It did need some fitting but is no surprise. I do like the sharp 25 lpi checkering which increases the grip better than the original cast magwell. I am looking forward to the ambi safety that will be coming from Chen Custom.

Magwell.
Absolutely a superior product. I replaced another magwell with this one and there is no comparison. The checkering is primo. USPSA single stack legal. Buy with confidence. Worth it.
