Has anyone here used a OWB beltloop type Blade-Tech kydex holster.Not the new cheaper injection molded type but the handmade one.I am thinking about getting a FBI cant one for a Glock.I would like to know how they are as far as fit and finish.Also has anyone had a problem with the beltloop screws working themselves loose?Lastly how does the cheaper injection molded holster compare to this one both lookwise and fit?
