The story
Founded in Detroit, Michigan, Cor-Bon/Glaser Ammunition originated when Peter Pi Sr. started making handgun hunting ammo in 1982 because the commonly available ammunition at that time was performing poorly. Pi noticed that hollow point ammunition would not expand and went about creating a line of ammunition with reliable expansion.
In 2017 the Company was sold to TA Perrine and moved to Wooster, OH.
In 2021 the company was sold again to an investment group out of Sandusky, OH,
