The rule of thumb seems to be that if the gun can quickly be withdrawn from the holster it is legal. If it can't be "quickly" withdrawn, but can still be fired while in the holster, then it's not legal. (Makes about as much sense as the infield fly rule, if you ask me...)I dunno either! There had to be a loophole found somewhere. Because just like Rathdown said, the High-Standard holsters were on the list. I remember well. I'll try to find out again tomorrow.
We have enough problem trying to get ATF to give us answers on what does or doesn't constitute "manufacturing".
