Does anybody know how a .32 H&R Mag. SP101 could be converted to fire .32 Blackpowder blanks only? Or do you know of a gunsmith who could do the conversion? Because of restrictions by government and schools, Track Officials are not suppose to use "open barrel" pistols on a school campus. However, there is nothing on the market that compares to the quality, function, or convenience of a good quality stainless revolver such as the SP101. I assume that the cylinder would be shortened and a barrel plug inserted to deflect the gas/wad explosion.
