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
Bought this for my Springfield Loaded. Fit and finish is outstanding and there was no blending necessary. I highly recommend this magwell for everything from concealed carry to competition.

SI Magwell (Blued)
The SI Magwell was an amazing upgrade for my 1911! It was incredibly easy to install even though I am fairly new to the 1911 platform. The only trouble I had was my 1911 has an ambi safety (the video demonstrating the install only has a left side) which made it a little different. But it fits perfectly with no modifying for a Springfield 1911 Operator. The blued finish is almost an exact match to the overall finish of the pistol as well and I am very satisfied with the look. I also really enjoy the checkering on the mainspring housing and find it is a vast upgrade to the stock texture the pistol came with. Very impressed with this products quality!

Chen SI Shooter Installed Magwell
I recently installed a Chen SI "Shooter Installed" Magwell on my Colt 1911, and I'm genuinely impressed. As someone who appreciates both performance and ease of installation, this product exceeded my expectations. Right out of the box, the quality was evident. The finish was flawless, and the contours were precisely what you'd want for a seamless integration. The moment I started the installation, I knew I was in for a good experience. Fitment was absolutely perfect. There was no slop, no forcing, just a smooth, precise union between the magwell and my 1911's frame. This isn't always the case with aftermarket parts, so it was a huge relief to see such a tight tolerance. What truly sets this magwell apart is how it blended into the frame right out of the box. Seriously, it looked like it was factory-installed. There were no unsightly gaps or mismatches in the lines. This speaks volumes about the meticulous design and manufacturing of the Chen SI "Shooter Installed" series. Even better, the installation only took a few minutes. This is truly a "shooter installed" solution – no gunsmithing required. If you're comfortable with basic firearm disassembly, you'll have this on in a flash. For anyone looking to add a magwell to their Colt 1911, I would wholeheartedly recommend this product. It offers a quick and easy solution that significantly improves reloading speed and consistency without any headaches. The perfect fit, seamless blend, and effortless installation make the Chen SI "Shooter Installed" Magwell a top-tier upgrade. You won't be disappointed!

Great product. Wish there were more finish options
It would be great if DLC and cerakote options were added to the finishes. Quality is top notch.

SI Magwell
The SI magwell went onto my new production Colt Competition perfectly. I followed the YouTube install video, which was really effective. No fitting required, no gap between the bottom of the grip and the magwell, and it mated perfectly with the internal flare of the grip. What an awesome upgrade to the look, feel, and function of the pistol.
