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 packages.
*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.

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.
