Advantages of the Flashbang is that females who wear form fitting pants/jeans and do not carry a handbag or satchel can still carry a deeply concealed small handgun. The fact that the firearm is held inside the strong core area of the body ensures an advantage in a weapons retention scenario.
Disadvantages of course is that the holster is almost a mandatory two-handed draw, with the offhand opening or raising the shirt and the string hand going for the firearm. This can take some time in a crisis situation. However, with practice it can be expected that the average female CCW carrier using a Flashbang holster can deploy the firearm in less than two seconds. Care must also be taken to make sure that you do not flash the off hand with the muzzle of the firearm and this tactic must be drilled and ensured for safety. See the video below for reference.
The Flashbang holster is the creation of Lisa Looper of Looper Law Enforcement LLC. The Looper family has been in the leather/holster business since 1938. After 7 years in the industry and countless times of trying to look like a “girl” while carrying concealed, Lisa began to develop the idea that has become the Flashbang.

Their motto is, “Play nice...Let the bad guy die happy!”
