I have used this type and it is flexible... capable of being worn both on the belt, behind the belt, or IWB. The only problem is that as soon as the gun is drawn it is impossible to reinsert it back into the holster with one hand... you must hold the holster open in order to reinsert it.
Since I wear my shirts tucked in, a "tuckable" holster was a must. I would have preferred the shield against the body, by that is available only in the custom holsters and I didn't have the patience for the long turn around time. I have found the holster comfortable, easy to put on and take off. The placement of the belt clip is such that almost anything other than a thin white shirt will provide cover for the rig. The tension screw holds the gun very will and there is just enough tensioning material at the mouth to re-holster with one hand... even though the other hand is going to be gathering your shirt to keep it out of the way. Not the fastest, but when you must dress so that you never know when you will have a coat on or off, it is an excellent approach.
I love a slide type holster. I generally use a generic style so I can pick any gun I want, to carry at that time. I used to switch between a Gov't model, Combat Commander, S&W model 19 4", a PPK/s, and a Colt Cobra using the same holster. That was Nirvana, fo me.
Yep. Pretty much the same. I hate all the IWB jobs I've tried and don't care for most OWB or belt holsters unless I'm in the field and carry open, but thought I might try one of these or a 3 position type pancake.
