(or the 95 gr RN bullet)for sales of the Split Nose for intended use in the 9 x19, cause the 105 gr swc is going to have feeding problems in quite a few guns. If, however, guys just want to CHECK what velocities CAN be had in 9x19, before rechambering to 356, the shorter swc bullet will suffice. They can simply work up loads to top velocities, chambering them by hand. Once a "spare" barrel is rechambered to the 356TSW, the .100" longer case will take care of the OAL of the shorty swc being too short for some mags. What happens is that when one rd feeds, the next rd is drug forward out of the mag lips, and just lays "loose" atop the mag. Not good. The 105 gr swc bullet has to be loaded so far "out" of the 9x19 case that the first grease groove is readily visible, and not all 9x19 chambers are cut deep enough to let such a rd be fully-chambered.
