So I purchased a second Shield, this time a 9mm Shield from BudGunShop. When it arrived, I tried to dissemble the slide but it wouldn't fully slide off. It appears the problem is the slide end cap assembly. It doesn't fully fit at the top and it seems to be preventing the slide from sliding off the lower. I never fired a shot in the thing - called Buds and they said its a warranty issue. Has anyone had this issue???
