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

SI magwell
I have a Colt CCU that I love, however the two piece magwell became wobbly...didn't effect function but my OCD couldn't put up with it...In comes the SI magwell..one piece and took 3 minutes to install. The fit is amazing. Hats off to Stan Chen and the SI magwell Thanks

Easy Install
Just installed my second SI Magwell, this one only took 15 minutes to install on my S&W E series 1911, flawless. My first install on my Colt Competition took longer (40 minutes) as it was the first one, great fit and function on both. Great product!

Dan Wesson Bruin
Went on in 3-4 minutes. Lined up perfectly. Matched factory blue. Better design than factory magwell on my kodiak. Buying another chen for 3rd Dan wesson. Why can't I upload pics to my review.

1911 SI Magwell
As advertised the Stan Chen SI Magwell was indeed an easy shooter installation. Great website showcasing products. High quality product and support. “How To Install” video very well done.

SI Magwell
This is the second one of these I have purchased to “spice up” a 1911. Excellent construction and simple fitment with common hand tools. If you can assemble legos and understand basic diagrams, this Maxwell will be a “Custom Looking” addition to your pet 1911 project!!

Absolutely the best. My second one and the fit was as good as the first one. One on a Dan Wesson and the second on a Springfield. Makes holding the uncomfortable (to me) straight mainspring housing grip much more comfortable. The superb magwell f
Keep up the good work......

SI magwell.....
I have not installed it yet (waiting on grips) it will be one of my upgrades when I do a trigger swap. I can tell you however that this thing is impeccable quality......amazing fit and finish. Can't wait to get it installed in a couple days and start blasting hardball through paper and into the berm l.o.l. Like I said though, GREAT quality and I can't wait to get it installed.
