The Broadside Profile
The features that create the bold looks and brute strength of the Broadside also helps further tame your gun's recoil. The Recoil-Ridge(TM) that runs midline, down both sides of the shroud creates a "carry-practical" version of what competition shooters call a "gas pedal". This keeps your support-hand thumb firmly connected to the gun's frame throughout the longest strings of rapid fire and when steadiness is demanded for longer-range accuracy. It makes a 40-cal or 357-SIG feel more like a 9mm, and a 9mm feel more like a 380-auto.
The Defender Top-Feature
The subdued appearance of the Defender is the preferred choice for image-conscious agencies, and individuals who prefer a simple and clean look. More than just aesthetics, the Defender provides the maximum level of protection when it comes to keeping dirt or debris out of your gun, which means greater reliability in any environment, whether that's the street, the outdoors or downrange.
The Bottom Profiles
The 'Classic' bottom profile was designed for GEN3 and GEN4 Glocks, and uses an extended Locking Block Retaining Pin to secure the Shroud to the gun's frame. The 'Access' profile was created for two reasons. First, to make it compatible with GEN5 Glocks, which allows the Shroud to be secured by the trigger pin. (GEN5 Glocks don't have a Locking Block Retaining Pin.) And second, to give shooters access to the Slide Lock while the Shroud is mounted. This makes the Shroud compatible with other devices, such as the LaserMax guide rod.
Adding thumb grooves to your Combat Shroud? not only adds additional styling to your gun, it also provides an additional gripping surface. This translates into less muzzle rise and better recoil management. Thumb grooves on Shrouds with Broadside profiles are the most aggressive at holding your thumb in place when shooting from full extension. While thumb grooves on Slimline models provide better grip than similar models with no thumb grooves, they have a less aggressive feel, which is preferred by some.
