I've heard fo guys running over 1,000 rounds through them but can't think it was only hardball?
What JHP or other defensive ammo are you Shield guys using?
Some have had problems with the Barnes X bullet, which would be DPX and the Tac-XP, my current load
for my CZs in 9mm.
Load options for me would be TAC-XP, Gold Dot, Hornady FTX, and Cor-Bon powerball.
