Review: Falco Falcon IWB Holster

In my experience,this type of IWB belt clip in unreliable in keeping your firearm stable with considerable body movement.Meaning,if your standing stationary it's fine.If your moving around or in physical contact with someone trying to put you away.It most likely will release from your belt.Just my opinion
I have seen booth good and poor clips like that. Some heavy duty ones that were practically impossible to open and cheaper ones which came off easily.

The only opening holster belt slot I currently use is the Tek-lock from blade tec holsters.
