Description Tech Specs
Simple installation by shooters - No gunsmithing needed!

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.

How to Install the Chen SI Magwell
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

5 of 5 Nice upgrade to my Ruger 1911 June 30, 2020
Reviewer: Bob W from Idaho  
Ordered the stainless and installed it on my Ruger Stainless Target II.  A perfect fit and did not require any 'fitting'.  SC makes a quality product and really make my 1911 look custom.  Used the inners from the Ruger's MSH and did the function check, all in all it was a piece of cake! Thanks Stan for a high quality product!

5 of 5 THIS should be your first upgrade May 14, 2020
Reviewer: Tekki from Bethlehem, PA United States  
When I got my 1911, over time I upgraded the recoil spring kit, the trigger spring, sear spring and magwell. All in that order. Had I known what I know I would have done the magwell first.

5 of 5 Absolute Artwork! May 14, 2020
Reviewer: David Norfleet from Clarkston, GA United States  
I have been searching for the right magwell for my Colt Competition.  I looked at several others, but as soon as I saw the Chen SI, I knew this was the one and ordered it.  Fit and finish are PERFECT!  Total drop in, no fitting required.  The checkering on the back grips well, but not enough to dig in, very comfortable.  The only thing I changed was the blasted finish on the side.  I sanded that to match the brushed stainless on the side of the pistol (Sorry Stan, I had to "make it my own").  Any 1911 I buy in the future will undoubtedly wear on of these!  As I said, Absolute Artwork!
