Experts in Firearms Technology, Design, & Use.

Firearms expertise can be complicated.

Obtaining such expertise for your client doesn’t need to be.

When a crime or tort includes the use of a firearm, a criminal defendant or plaintiff-in-tort needs the consultation and testimony of a firearms expert. If you are defending your client in a firearm crime, a violation of municipal/state/federal firearms statutes, or if you are moving your civil plaintiff’s case forward, you need a technical firearms expert with a winning history on your litigation team.

We are available to discuss the actual and potential case merits and defenses, identify issues, and make expert recommendations.

Testimonials

“Based upon Greg’s knowledge of automatic and semi-automatic weapons, we were able to successfully cross-examine the Commonwealth’s alleged ballistic expert and expose the weakness in their case. G&G Firearms are professionals who maintain a high-degree of integrity, and I would not hesitate to use them in any firearms case.”

Arthur Tourkantonis, Attorney at Law

“Thank you for your expert assistance in helping us evaluate a recent case involving firearms safety. You conducted your investigation professionally, discretely, and confidently, and I do not hesitate to recommend your services as a firearms safety expert.”

Jonathan D. Sweet, Counsellor at Law

“All your hard work in identifying the firearm, getting the appropriate instruction manuals, viewing and identifying the weapon, and then finding a similar weapon and doing a video for me clearly made the case for the defendant much, much better and ultimately contributed greatly to obtaining the favorable result we did. I cannot too highly recommend G&G Firearms to any other person who needs a true firearms expert.”

Ray Buso, Attorney at Law

“Performing services as a professional gunsmith, firearms trainer, and forensic ballistician, I highly recommend Mr. Danas as a qualified ballistician / forensic expert.”

Steven S. Kim, Esq.
