My normal footwear is western boots, often with 15 to 17" tops. I have an AirLite Smith Model 317 that I would like to conceal in the boot tops. Have never worn or even seen a IWB holster so have no idea if it would convert, but I am looking for a holster that would clip to the boot top and securely hold a holster, preferably inside the boot. But, if need be, and if it were secure enough, I would wear one that secured a holster on the outside of the boot top and wear my jeans over the boots. But, it would have to be secure because in normal ranch work it would be easy to loose a gun that was outside the boot.
