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.

Shooter installed Magwell.
It was definitely not drop in for any of my Tisas 1911s. The forward portion of the well was NOT designed for any gun that has a beveled or angled opening adjacent to the 90deg for the mag floor plate opening. If your gun has anything other than a 90 at the bottom of the front strap be prepared for some mods. Also the shelf that the grip safety moves over is cut too short for the grip safety to release and had to be relieved by 3/16” to allow the grip safety to activate. The part is made exceedingly well, but it would be nice to include the pin and or small parts for $149. These issues may be related to a peculiar situation with the Tisas brand but the shelf depth for the grip safety is not. I don’t know why the two I ordered needed to be relieved so as not to interfere with the gs but they did.

Wow....just, WOW!
Not only is this one of the most practical mods you can make to your 1911 , it is hands down the most beautiful. A true example of the ideal blend of form and function. I almost hated to give one as a Christmas present for a friend, as I wanted to keep it for myself! Wonderful, friendly communications too!

Chen SI Magwell
Fantastic fit and finish! I have large hands and this eliminated the sharp point on the butt of the gun. Nothing but a pleasure to hold onto in my hand. Thanks so much!
