Pistols must be stainless steel or
carbon steel and in stock, unmodified condition. Currently we are not accepting
aluminum alloy frames. Nickel plated firearms must have the nickel finish
stripped/removed prior to machining.
Of course, the frontstrap
must be smooth and not have any checkering or other frontstrap treatment
already cut if you are selecting the Gen2-ProTrac package. Bobtailed frames are not suitable.
The following brands are
suitable for our machining services: Colt, Springfield, Dan Wesson,
Kimber, Wilson, Nighthawk, Ruger, Remington, JEM, and Caspian, with full
length grip frames (i.e. Government or Commander/Champion sized). If your frame
is not on this list, please drop me an email.
The Gen2 is machined as one piece, integral with the Mainspring Housing. The entire bottom of the full size pistol frame is shortened by .300”, by machining, to accommodate the magwell. No length or width is added to the pistol. Concealability, portability, and the overall handling of the pistol is not compromised. If you can conceal a standard 1911, you will be able to conceal a Chen Magwell’ed 1911 with the exact same ease. The Chen Magwell Gen2 is attached to the pistol frame via the Mainspring Housing Pin, which is relocated from its original position.
The Chen Magwell Gen2 adds two Side Impact Reinforcement Tabs, which snugly engage against the sides of the pistol frame, and provide a tremendous amount of lateral support to the magwell so it will not twist from any side impact.
The Chen Magwell Gen2 allows for the removal of stuck magazine by providing access to the toe of the magazine so that the magazine can be forcefully extracted in the event it becomes stuck in the pistol. This is made possible by 1.) front magwell geometry which has been considerably reduced compared to traditional weld-on magwells and 2.) a pronounced access notch has been machined in front.
The Chen Magwell Gen2 delivers speed and consistency while reloading under stress. Using sophisticated CAD design and CAM driven machining, the magwell opening is opened up as wide as possible without adding bulk. The entry angle is optimized for the smoothest reloads possible. The Chen Magwell Gen2 is custom installed, contoured, blended, and dehorned. A generous roundbutt is machined and hand sculpted into the part itself, enhancing shooting and carry comfort. The proprietary Chen BevelBlock™ is a block of extra material in a key location at the rear of the magwell, which allows a seamless, gap-free blend with the pistol.
Our custom installation includes a dramatic, custom blend of the magwell into the pistol frame itself. This makes the transition from magwell to pistol even more effortless in function and more seamless in appearance. The blend goes as far up into the pistol as possible, assuring the most efficient entry angle.
The installation is completed with custom fitting of double diamond G10 grips which are made for us by our friends at VZ Grips. Please note if you wish to change grips in the future, VZ Grips will soon supply the "Chen Magwell Cut" as an option. They will come shortened for the magwell, with relief cuts for the Side Impact Reinforcement Tabs, and just a little extra material for final fitting.CHEN
PROTRAC CHECKERING™Called Progressive Traction Checkering™ (or
ProTrac™ for short), this frontstrap texturing is an exclusive innovation from
Stan Chen Custom. As the name implies, this distinctive texture is specifically
designed to give the 1911 shooter a degree of traction which is proportional to
the amount of grip force applied. So what you have is rock solid traction in
rapid fire, but if you have to flip the pistol to hit the mag release for
reloads, it just slides smoothly in your hand when you momentarily let up on
the grip.Because of the wide spacing of the lines, the
individual diamonds are larger and more robust than traditional diamonds. Yet,
they are NOT overly abrasive because the diamonds have a more gradual side
profile and the depth at which they are cut.
ProTrac™ Checkering is available for the front
strap of your stock 1911 frame. Included is a sweeping high cut of the
fronstrap and trigger guard, which also gets your hand as close as possible to
the axis of the bore for increased recoil control. It is hand finished to
produce the greatest comfort and graceful, flowing lines.
ProTrac is also offered on a Stan Chen
Mainspring housing which can be purchased with the installation of a Chen
Mainspring Housing or within the Maxbevel with ProTrac machining package.
