Shotgun barrel retainer in which the barrel is pivotable about a hinge pin supported by the laterally spaced arm portions of the gun frame by means of a depending barrel lug disposed between the arms of the frame and having a semi-cylindrical recess engaged with the forward portion of the hinge pin. A coil spring urges the barrel outwardly to maintain the barrel lug firmly engaged with the hinge pin having at one end a shoe or saddle member engaged with the cylindrical surface of the hinge pin opposite the barrel lug and being compressible between the hinge pin and a second barrel lug toward the fore-end of the barrel. A resilient leaf spring is carried on the hinge pin and is disposed between the frame and the barrel lug. The leaf spring, in combination with the coil spring and shoe member, serves to retain the barrel in fixed position on the frame and prevents undesirable relative motion therebetween when the barrel is pivoted to an open position.
