Firearms Services

PFS extensive firearms expertise has seen us instructed in complex, sensitive and high-profile cases in the UK and across the globe. Our expert witness testimony has been pivotal in the full range of firearms offence cases. We have played a vital role in the interpretation of firearms law in complex technical cases and have advised both the Home Office and Law Commission on firearms classification matters.

We also have an in-depth knowledge of all firearms licensing compliance issues and hold Home Office Section 5 approval that enables us to examine all forms of prohibited weapons and ammunition. We can prepare reports for use in criminal and civil cases involving many types of firearms, ammunition and imitation firearms, including airguns, hand guns, stun guns, deactivated weapons, shotguns and rifles.
