Michael R. Grimler, Firearm Instructor



Experience, Training, and Certifications

I bring several years of experience with my formal training as a firearms instructor.

My firearm instructor experience started when I was approached by the range staff at the Orange County Sheriff's Department in Orange County, CA, shortly after I graduated from the sheriff's academy as a California POST-certified Level 1 reserve deputy for OCSD and asked me if I would like to join the team. Of course, I said yes. They sent me to the FBI's Police Pistol and Shotgun Instructor course and soon after, assumed duties as an adjunct instructor. I was also sent to H&K's MP5 submachine gun operator and instructor courses since OCSD's SWAT team was using the MP5 at the time.


I was instrumental in instructing OCSD deputies during the department's transition from revolvers to semi-autos.


I also taught "Use of Deadly Force" and "Combat Handgun" classes to new recruits in the Basic Academy. And, provided incumbent deputies with training on the Remington 870 shotgun.


In addition to being a certified instructor (Instructor #21) for the New Mexico Concealed Carry training, my formal firearm training includes:
