PDWs...and other small arms.

I remember the days of 9x25 Dillon in IPSC - in Open class comped and red dot race guns. Muzzle blast was horrendous and noone wanted to be the Range Officer with that shooter. Tore up the steel targets in some cases. I remember discussions that no one was interested in a stock pistol in 9x25. For sure, it has velocity and penetration.
