Definitions

• the invention relates to a magazine catch for small firearms, especially self- loading pistols allowing the user to release the magazine in the firearm grip with either right or left hand by pressing the magazine catch transversely arranged in the upper part of the firearm grip.
• Document No. DE-OS 2905770 describes a magazine catch, the controlling element of which comprises of a pin that is arranged in the firearm grip transversally to the shooting direction and which can be moved axially and the ends of which protrude from the grip.
• the magazine catch for small firearms, especially self-loading pistols allowing the user to release the magazine in the grip with either right or left hand by pressing the magazine catch transversely arranged in the upper part of the handgun grip based on this invention, the principle of which is that the magazine catch comprises of a cylindrical part finished with a pushing surface at one end and installed in the transversal bore in the firearm frame in a sliding way and of a spring-loaded button installed on the other end of the cylindrical part in a swinging way and equipped with a locking - latch adapted to slide into the recess in the opposite part of the inserted magazine. Between the cylindrical part and the spring-loaded button there is a compression spring.
• the cylindrical part is equipped with a superficial groove in which the end of the longer arm of the return spring that brings the cylindrical part into the resting position is positioned freely and the shorter arm of the return spring is positioned in a frame.
• the transversal bore is equipped with internal shouldering, both for the purpose of defining the resting position of the magazine catch.
• Fig. 1 presents a side view of the self-loading pistol frame portion without grip panels with the exposed spring-loaded button of the magazine catch and with the magazine in the frame grip
• Fig. 2 shows a axonometric view of the part of the frame comprising the grip
• Fig. 3 presents the magazine in an axonometric view
• Fig. 4 presents the set of parts of the magazine catch
• Fig. 5 shows a section of the pistol frame on the A-A plane indicated in Fig. 1
• Fig. 6 is a magnified part of Fig. 5
• Fig. 7 presents magnified detail of B shown in Fig. 5, Fig.
• Fig. 8 presents the magnified set of parts of the - magazine catch without the return spring
• Fig. 9 presents an axonometric view of the assembled magazine catch in magnified representation with the cylindrical part partly exposed allowing you to see the arrangement of the compression spring in the bore
• Fig. 10 shows a section of the part of the pistol frame where you can see the attachment of the return spring the longer arm of which is engaged with the magazine catch.
• a transversal bore 13 is made in which the cylindrical part 20 of the magazine catch 2 is arranged in a sliding way while one of its ends with the pressing surface 21 protrudes out of the frame 1 and is within the reach of the thumb of the right- handed user.
• the shooting direction is marked with an arrow 0 in Figs. 1 , 2 and 5.
• the cylindrical part 20 is equipped with external shouldering 22 that forms a stop together with the internal shouldering 14, see Fig. 7 delimiting the movement of the cylindrical part 20 by pressing the magazine catch 2 to the right, seen in Figs. 2, 5, 6, 7 and 10.
• a holding console 23 On the other end of the cylindrical part 20 there is a holding console 23 with two opposite coaxial holes 24, 24' and a recess 25 that is continued with a holding bore 26 seen in Figs. 6, 9, 10 and with a stop 230 the function of which will be described below.
• the magazine catch 2 comprises a spring-loaded button 27 with a protrusion 270 and a holding hole 271 and it is equipped with a locking latch 272 and supporting surface 273.
• the spring-loaded button 27 is attached in a swinging way to the holding console 23 with a peg 231 that passes through the coaxial holes 24, 24' and the holding hole 271.
• a compression spring 261 leaning against the supporting surface 273 that acts against it with its flexible pressing force.
• the transversal bore 13 has a longitudinal extension 131 that is continued with the holding console 23, protrusion 270 and partly the extended external part of the spring-loaded button 27 protruding from the upper part of the grip 11 that can be controlled by the thumb of a left-handed user.
• the swing of the spring-loaded button 27 is limited by the stop 230 shown in Figs. 6 and 8.
• the magazine 3 has a recess 33 on the transition of the front wall 31 to one side wall 32, see Figs. 3 and 6 on the level where with the inserted magazine the locking latch 272 of the spring-loaded button 27 is located.
• the shooter uses the thumb of the right hand to press the protruding pressing surface 21 of the cylindrical part 20 of the magazine catch 2. This way he/she overcomes the resistance of the longer arm 291 of the return spring 290 with simultaneous movement of the cylindrical part 20 in the transversal bore 13 as well as drawing-out of the spring-loaded button 27 until its locking latch 272 leaves the recess 33 of the magazine 3 in the grip 11. This way the magazine 3 is released and it falls off the grip 11 of the pistol.
• the magazine catch 2 can also be controlled with the index finger of the right or left hand.
• the shooter is a right-handed person, he/she controls the magazine catch 2 by pressing the spring-loaded button 27 with the index finger of his/her right hand.
• the shooter controls the magazine catch 2 by pressing the pressing surface 21 of the cylindrical part 20 of the magazine catch 2 with the index finger of his/her left hand.
• the invention is not in any way limited to the described and presented sample embodiment and it can also be easily applied in the case of other firearms, e.g. submachine guns.
• the invention can be utilized industrially mainly by manufacturers of small firearms within terms of innovation of these arms, mainly self-loading pistols.
