My OP was back on April 13, 2010. The thread took a turn on a couple of variations for 'free spin' so now I'm just a bit confused. I have a NM Blackhawk, Bisley, .45. I think I want it to free spin. I saw the links of how to alter the 'top' leg of the pawl, but I read that in some models the lower leg of the pawl helpS align or index in some way. Do I need to alter the lower leg of the pawl, the 'window' in the frame or leave both ALONE.??
