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 housings which can be included within the machining package. Prices and details can be found below.  Click here for more information

*Please note, on Stan's full house pistols, the ProTrac checkering on the rear wraps around the mainspring housing onto the sides of the pistol frame. Customer pistols sent in for this service will be checkered on the mainspring housing only, due to extreme variations among pistol manufacturers.

CHEN MAGWELL GEN2 INSTALLATION

 

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.

The Chen Magwell Gen2 Installation service does NOT include our ProTrac™ checkering treatment. If you desire ProTrac™ checkering as well, please see the Gen2 and ProTrac™ Package below. 

Pistols must be stainless steel or carbon steel. Currently we are not accepting aluminum alloy frames. Nickel plated firearms must have the nickel finish stripped/removed prior to machining. 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.

Chen Deluxe Maxbevel

Magazine well with Chen Deluxe Maxbevel treatment


The Chen Maxbevel™ treatment transforms the bottom of your pistol into an ergonomic, elegant masterpiece of effectiveness. The Chen Maxbevel™ treatment gives the largest available magwell bevel without an add on part.  

The Chen Maxbevel™ is seamlessly cut into the mainspring housing as far to the rear as possible for reliably fast reloads. This is done using our unique, proprietary Chen Mainspring Housing. The Chen MSH allows for this seamless cut to be performed without the unsightly gap which is common to other attempts at enlarging the bevel to the rear with a standard mainspring housing. 

Magazine well without Chen Deluxe Maxbevel treatment

Magazine well without Chen Deluxe Maxbevel treatment

Beyond just enlarging the opening, the entire area is hand blended and dehorned into an ergonomic, flowing unit. The front of the mag well is cut and shaped to eliminate the sharp corners on stock pistols, which can cut the shooter during fast reloads.  

RoundButt                                                                                                        As part of the Maxbevel™ treartment, your pistol will receive our "RoundButt" treatment, which provides a significant increase in comfort while both shooting the pistol, and carrying it concealed. To accomplish this, the back heel of the pistol, to include the frame and mainspring housing, is generously blended and radiused into an integrated, comfortable contour. Combined with our ProTrac™ and HighCut, the Roundbutt is part of what makes the pistol feel as though it "melts" comfortably in your hand. This combination is available as part of the Chen Maxbevel™ and ProTrac™ Package, see below.

Modify Slide Stop

 

The slide stop pin is shortened to sit flush with the frame. This prevents the slide stop from being inadvertently pushed out of the frame while the shooter has his finger rested along the side of the pistol during administrative functions such as loading or press checking the pistol.

To aid in the reassembly of the pistol, the slide stop hole of the frame is precisely countersunk, and the end of the slide stop pin is chamfered.

Details

 

Each month, I carve out time in my schedule, to allow for a limited number of slots available for custom machine work. Approximate work dates for the upcoming month are posted on our online store. Pistols must be received in my shop before the work date. Only the machine work listed here can be performed, as I simply don't have time in my schedule to tune or set up customer pistols on an à la carte basis (i.e. reliability, action work...).

To order custom machine work for your stock 1911, please follow the link to our store. You will find shipping information there as well.

*Note that certain models of 1911s which appear to be black (most notably Kimber) are actually a mixture of stainless steel and carbon steel parts. As such, these pistols cannot be blued. An alternate coating such as Cerakote should be applied.
