I love the Dean Adams inside the thigh holster.
It's like spandex boy shorts and places the gun inside the left thigh. (For right handed shooters)
I can obviously wear it with dresses and long shirts & leggings, but I also wear it with jeans and long sweaters....I just wear it on TOP of the jeans.
The following statements are practice with a 3 person checked & cleared pistol.
I've had my husband grab me as if he were going to kidnap me, from every position we can think of, and I can still get to it.
I can't actually get a hit sometimes, but I can get a grip and pull the trigger every time..
The bang should disrupt the bad guys OODA loop enough for me to pull away and decide what my next move needs to be.
My pastor says I'm his secret weapon because no one would ever suspect I was carrying a gun with the sweater dresses I wear. Plus I'm 5'3" 125lbs which works to my advantage because I don't look like a threat at all.
Other than that, Im a minimalist and prefer a simple kydex holster.
With jeans and a normal length shirt, I wear the undertech backwards so the gun is in the apendex position.
