WPG holsters are made from top grain cowhide, and are accurate in every detail right down to the rivets. These are widely recognized as the best reproductions available anywhere. Leather is undyed natural finish, which turns russet brown naturally with age and use.
The fit is very tight, just like originals, and new holsters should be wet formed: Wet the inside of the holster with water, shove in a well-oiled, plastic wrapped pistol, and let dry. The holster will fit perfectly after this operations.
