Hi, I have a S&W 638 J-frame. I would like to find an ankle holster that is all of the following: secure (keep gun secure), secure (holster does not get loose on my leg), and as concealable as can be. I would be wearing it with dress pants while at work. I won't say price is no object, but I am willing to pay what it costs to get something that is very secure and very concealed. This is for while I am at work and I cannot have the weapon falling out of the holster under any circumstances and cannot have it look like there is a tumor growing off my leg. Any recommendations?
