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

Blued SI Magwell
Looks amazing. Installed on a Para-Ordnance Elite, and it blended perfectly with the frame.

Amazing fit and finish
I bought this for my Smith & Wesson 1911 pro. Very easy installation especially if you have someone drop the retainer pin for the main spring. If you have an ambi safety pull both grip panels off and it goes quick.

Stainless, Government size, SI magwell.
This is very well made. 9 out of 10. I bumped it down one notch only because I would have liked the checkering to be sharper. A person can always dull the tips a little with emmory cloth if they are too sharp but you can't make them sharper if they are too dull when you get it. All in all...... The checkering is sharp enough and perfectly fine for most folks but I would have liked it sharper and then dull it to my specific taste. As received...... It will not slip into the frame of my brand new Les Baer pistol as it is about 0.002" too wide so I will have to fit it a little. I also purchased a Wilson Combat magwell and it doesn't fit either. It measures the same as the Chen part. The Baer frame may be slightly undersized.
