Michael R. Grimler, Firearm Instructor
Experience, Training, and Certifications

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

My firearm instructor experience started when I was approached by the academy 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.

They noticed that I was at the range almost every weekend day, that I was a decent marksman, and asked me if I would like to get trained as an adjunct instructor and join the firearm instructor 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 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 taught "Use of Deadly Force" and "Combat Handgun" classes to new recruits in the Basic Academy, and provided incumbent deputies with recurring training on the Remington 870 shotgun.


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