The Spring Special(TM) features a quick-release thumb break and a reinforced top band around the holster mouth. This prevents the holster from collapsing and allows one-handed reholstering. Our extra strength "quick-on" spring clip features a hook configuration for maximum retention, which prevents the holster from being drawn with the gun. The Spring Special(TM) is made from top grain cowhide and molds to you and your weapon over time, creating a comfort unique to your body. It works great in the summer too! NOTE: Not compatible with red dot optics
