Court hears 3D printed guns are becoming ‘more prevalent’ as man jailed for four years – The Irish Times

Craig McKeever, 21, has been sentenced to four years and six months in prison after pleading guilty to the possession of a 3D printed .22-calibre pistol. The Dublin Circuit Criminal Court heard that the weapon and three rounds of ammunition were found during a Garda stop in the Inchicore area.

The sentencing hearing highlighted a growing security concern regarding the accessibility and nature of non-traditional firearms. The court was told that the weapon was concealed under a bulletproof vest worn by McKeever.

The Rise of 3D-Printed Firearms

Detective Garda Niall White testified that 3D printed guns are becoming “more prevalent” in the country. He described these weapons as being “made of polymer,” which makes them small, easy to conceal, and undetectable by metal detectors.

Det Gda White noted that while 3D printers are purchased for various reasons, “if you get the correct programme, you can print a lethal firearm like this.” The Garda Technical Bureau confirmed the seized army-green pistol was in working order and capable of discharging ammunition.

Details of the Arrest

The incident occurred on June 24, 2025, when gardaí spotted McKeever and another man entering a taxi. Upon searching McKeever, officers discovered cannabis worth approximately €500 in his jacket pocket.

As officers unstrapped a bulletproof vest McKeever was wearing, the .22-calibre pistol fell to the ground. The weapon was loaded with one round, and two additional rounds were recovered.

Defense and Personal Circumstances

During the proceedings, barrister Kieran Kelly stated that McKeever’s entire family had received notices from gardaí regarding verified threats to their lives. It was noted that McKeever’s family home had been set on fire in July 2024.

McKeever claimed he was wearing the bulletproof vest due to these threats and told gardaí he had “picked it up to deliver it.” He denied carrying the weapon for personal protection, stating he was “just delivering.”

Court Ruling

Judge Elma Sheahan stated the court was “only too aware of the trauma and detriment caused to society by the use of guns on the streets” of Dublin and nationwide.

Taking into account McKeever’s 14 previous convictions—including drug, theft, and road traffic offenses—the judge ruled that the custodial threshold had been crossed. McKeever received a sentence of four years and six months, with the final six months suspended on strict conditions.

Future Implications

The prevalence of polymer weapons could lead to increased Garda scrutiny of 3D printing software and distribution networks. Law enforcement may also seek new technological solutions to detect non-metallic firearms in public spaces.

Given the verified threats mentioned in court, there may be continued monitoring of the feuds associated with this case to prevent further escalations.
