Well there appears to be 2 types of holders for sale out there; 1)Version made by Mark Otto, sold at 3Gunstuff 2)California Competition works, same style but attached differently? So on to the questions, since I can't compare them side by side physically, I wondering if there are some end users that can comment on either? quality? belt attachment preference? Overall satisfaction? Thanks Mark Otto, 3Gunstuff California Competition Works Wanna kill these ads? We can help!
