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 "Shooter Installed" Magwell
Replaced a SA Magwell which served it’s purpose for the time, but the Chen SI Magwell is a cut above the rest. The Magwell arrived super fast and installed without a problem. I highly recommend this Magwell. The M&M’s were a nice touch also!

SI Magwell
I ordered an SI magwell. Delivery was prompt. The part was machined perfectly. It was easy to install. It fits and looks great on my stainless Colt Competition Series. No issues with use at the range. It’s the nicest and most well thought out aftermarket part I have ever purchased for a gun. A+

Chen SI. Magwell for SA 1911 loaded
Best magwell for the money. I like how it’s beveled and smoothed out on funnel. It’s seamlessly fit on my SA1911. Highly recommended and would buy another one for future 1911 purchases👍👍👍

Chen SI Magwell is fantastic!
I ordered the Chen SI Magwell because I needed something to help me make faster magazine changes in my 1911. I have never done any gunsmithing on my guns, so I was a little hesitant about installing this myself. The video instructions made it so clear that I had no trouble doing the installation myself in about 15 minutes. It looks beautiful and I'm sure it will improve my reload times at the range.

SI Magwell
I’ve now purchased my second Magwell and I could not no happier with the quality of work you put into your product. The first Magwell was installed on a Springfield Ronin Operator. Your 25LPI magwell along with the 25 LPI front strap checkering, the entire grip frame looks factory. The quality of machining is first rate

Great Product!!!
I bought the SI Drop-In Magwell for my new Kimber Custom II TLE and it came well packed with a bag of peanut m&m's. The magwell installed in minutes with no modifications, a true drop-in product. The finish matches perfectly and allows for super fast reloads with the WC Elite 8rd mags that I have. Would definitely recommend to fellow 1911 enthusiasts.
