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

I am a New Mexico–based firearms and defensive use-of-force instructor with nearly two decades of experience in structured training environments. My instructional background is grounded in formal law-enforcement education and has evolved into a long-standing civilian training practice focused on safety, lawful decision-making, and responsible defensive force.

​

My instructor development began in California after completing reserve deputy training and serving as a POST-certified Level I Reserve Deputy. Following graduation from the sheriff’s academy, I was invited by academy range staff to pursue formal firearms instructor training based on demonstrated proficiency, consistency, and professionalism. I subsequently completed federal and manufacturer-level instructor courses and served as an adjunct firearms instructor supporting recruit and incumbent training programs under agency oversight.

 

During this period, my instructional duties included firearms safety, marksmanship fundamentals, lawful use-of-force instruction, and structured weapons transition training conducted in accordance with approved policies and curricula. All instruction was delivered within defined training standards and accountability frameworks.

 

Since relocating to New Mexico, my instructional focus has been exclusively civilian. I am a New Mexico Concealed Handgun Carry Instructor and provide training centered on lawful defensive firearm use, proportionality, de-escalation where appropriate, and risk mitigation. My courses emphasize compliance with state law, sound judgment under stress, and responsible carry practices for private citizens.

 

I do not teach law-enforcement tactics. My instruction is limited to civilian defensive contexts and is designed to promote safe, ethical, and legally defensible outcomes.
