The bite trigger works basically the same as the electric models. Mouth piece mounts to gun with Velcro strap and is operated by biting down on it. You can "feel" your trigger. The BT100 easily attaches to guns trigger guard with mounting screws. Extra mounting plates are available if you want to have multiple guns ready.
If safety is on trigger please specify. If safety isn't on trigger either model will work.
