Finish Protection
Cowhide linings provide a smooth surface against the finish of your handgun. Softer linings, such as suede, can attract and hold small pieces of debris that can scratch the finish of your weapon. Cowhide will not.
Longevity
According to Tucker Gunleather of Houston, Texas, having a cowhide lining will increase the life of your holster by 50 percent, particularly if you wear your holster on a daily basis.
Security
Since cowhide is a strong, rigid leather, a holster made from this material
will hold your pistol more securely, making it less likely that your pistol
will slip out of position.
