Gun charges in Missouri & Kansas carry mandatory prison time. Armed Criminal Action adds 3+ years. Call Devkota Law Firm: (816) 207-4255. Free consultation.
Looking for the best gun crimes defense attorney in Kansas City? Gun and weapons charges carry mandatory prison time — with no second chances. Armed Criminal Action alone adds 3 years consecutive. A conviction means prison, lost firearm rights, and a felony record that follows you forever. Call Devkota Law Firm Now to fight these serious charges with an aggressive defense.
Firearms charges in Kansas City sit at the intersection of state law and federal law in a way that creates serious risks most defendants do not fully appreciate until it is too late. Missouri is generally protective of Second Amendment rights and permits open carry without a permit. Kansas similarly allows permitless carry. But both states impose strict prohibitions on firearms possession by individuals with prior felony convictions, domestic violence convictions, or while under indictment. And when federal law becomes involved — through the use of a gun in drug trafficking, possession by a prohibited person, or unlawful transfer — the penalties escalate dramatically.
Our Kansas City weapons defense attorneys handle everything from unlawful possession charges for individuals who did not know they were prohibited persons, to armed criminal action allegations layered on top of assault or robbery charges, to federal firearms trafficking indictments. We understand the strategic importance of these charges and defend them with the same rigor we bring to the most serious violent crime cases.

Armed Criminal Action: Missouri’s Most Dangerous Enhancement
Missouri’s Armed Criminal Action (ACA) statute is one of the most punitive sentencing enhancements in the country. If you are convicted of a felony AND used a dangerous instrument or deadly weapon in committing that felony, the ACA charge adds a mandatory minimum of three years in prison — served consecutively, not concurrently, with the underlying sentence. ACA cannot be suspended, is not eligible for probation, and cannot be served as SIS. It is designed to stack years onto sentences for anyone alleged to have used a weapon.
We fight ACA charges by attacking the underlying felony conviction, challenging whether the item at issue qualifies legally as a ‘dangerous instrument,’ and litigating whether the weapon was actually ‘used’ within the meaning of the statute.
Federal Firearms Charges
When a gun charge involves interstate commerce — purchasing a firearm across state lines, trafficking weapons, using a firearm in connection with drug distribution — federal jurisdiction applies. Federal firearms prosecutions are handled by the United States Attorney’s office and carry mandatory minimum sentences under the Armed Career Criminal Act (ACCA) and 18 U.S.C. § 924(c). Our attorneys have experience in federal criminal defense and understand the critical differences between state and federal plea negotiations, sentencing guidelines, and appellate procedures.
Restoration of Firearm Rights
Missouri and Kansas both provide legal mechanisms for restoring firearm rights lost due to prior felony convictions in certain circumstances — including expungements, set-asides, and gubernatorial pardons. We advise clients on eligibility and pursue rights restoration through the appropriate legal channels when possible.
