Firearm with barrel state verification device

A firearm comprising a main body and a barrel, wherein said barrel extends starting from said main body, and a verification device suitable for verifying and detecting the presence of partial or total occlusions in the barrel or variations of cross-section, such constituting an anomaly of the barrel status, wherein the device comprises receiver means, on the firearm, suitable for detecting a detected signal derivable from an emitted signal, influenced by said anomaly;

• wherein the verification device comprises control means, operatively connected to the receiver means and/or to emitter means suitable for producing the emitted signal,
• wherein the control means are suitable for detecting and measuring a variation of the detected signal from an expected signal, deriving from the emitted signal in predefined conditions of the firearm, due to the presence of said anomaly;
• wherein the firearm further comprises signalling means, on the firearm, operatively connected to the control means in such a way that, in a configuration in which said control means detect a variation of the detected signal compared to the expected signal, the signalling means signal said detection to the user and/or prevent use of the firearm.
