Certified GLOCK Armorer

Advanced Glock Armorer Certified

My name is John Goldsboro Jr., VP of Training for S1 Firearms Training. I am a also a Certified Glock Factory Advanced Armorer and gunsmith located in Tampa Florida. I specialize in Glock pistols and their accessories. I am a retired New Jersey State Trooper (TEAMS) and have been a Law Enforcement Firearms Instructor since 1996. I am a lifelong shooter and NRA member, Law Enforcment & Private Armed Security Firearms Instructor & Advanced Tactical Instructor.

Glock Certified Armorers must be recertified every 3 years. To become a Glock Armorer you must be a certified gunsmith, certified firearms instructor, Law Enforcement Armorer or a GSSF member. Glock Amorers can help Glock owners with diagnosing problems including known warranty issues. Some of these are free through Glock warranty, and a Glock Armorer can assist you in this determination. I can run the annual function check, modify or upgrade the Glock with factory parts, adjust the sights, or add new sights.

Whether you need magazines, improved sights, target shooting modifications, specialized tools, Glock memorabilia, or the spare parts and springs to keep your Glock running right, I have it all for you.

I take pride in offering my customers superior service: extensive product knowledge, very rapid shipping, and fair prices.

Though I recommend using a certified Glock factory armorer to do any modifications to your Glock pistol, many mechanically minded shooters actually do it for themselves. Glock pistols are easy to work on. All you need is a Glock armorer’s tool and a bit of instruction.

Got a Glock question? Email me and I’ll do my best to reply very quickly.

Thanks, John.
