Does anyone know of a decent holster for the S20? I prefer something without a velcro flap, as the velcro seldom lasts long for me and then the flap sticks up (e.g., the FourSevens holster for the Quark lights). A topless holster, with elastic for retention, or a holster with a flap using a snap or other non-velcro closure would be preferred. I have taken velcro-flapped holsters and tucked the flap inside the body of the holster alongside the flashlight. That works OK, but the ucovered velcro on the outside of the holster then sticks to and destroys some shirt fabrics. Maybe a good quality velcro in a long strip might work, but the little small dime-sized patches of velcro common on cheap holsters just don't cut it in my experience. Thanks!
