(17) In the configuration, the slide (10) is configured to be provided on a frame (not illustrated) of the handgun and be moved horizontally toward front and rear sides, thereby moving a bullet in a magazine (not illustrated) to a location at which the bullet can be fired and causing the handgun to come into a loaded state.

(18) As illustrated in FIGS. 1 and 2, the slide (10) is formed to have a predetermined length based on the frame of the handgun, and an undersurface of the slide (10) has an accommodation groove having a predetermined depth into which a barrel (not illustrated), a recoil spring assembly (not illustrated), or the like is accommodated.

(19) A mounting unit (11) having a predetermined length in a front-rear direction is formed on the rear side (rear sight position) of the slide (10), and the mounting unit (11) is formed to have a flat surface on which the adapter plate (20) to be described below can be mounted by sliding in a horizontal direction.

(20) In addition, the mounting unit (11) has a rail unit (12) formed to project by a predetermined height and have a predetermined length in the front-rear direction, and coupling protrusions (12A) having a predetermined size are formed to project from both side surfaces of the rail unit (12). In this manner, the rail unit (12) and the coupling protrusions (12A) form a T-shaped cross section.

(21) In this case, the coupling protrusion (12A) can be formed all along the length of the rail unit (12), or a plurality of coupling protrusions (12A) can be formed to have a predetermined length in a front-rear direction of the rail unit (12).

(22) In a configuration of the rail unit (12) and the coupling protrusions (12A) described above, the adapter plate (20) is fitted and assembled into the mounting unit (11) by sliding horizontally from a rear side toward a front side in a state of being in close contact with the mounting unit (11).

(23) In addition, an insertion groove (12B) having a predetermined depth is formed on a rear side of the rail unit (12), and a lever (13) having a predetermined size is rotatably provided in the insertion groove (12B). In this respect, as illustrated in FIG. 3, the rail unit (12) has a through-hole (12C) having a predetermined diameter which penetrates both side surfaces of the insertion groove (12B), and a coupling pin (14) having a predetermined length is inserted to penetrate the through-hole (12C) as illustrated in FIG. 4 such that the lever (13) is fixed to have one end that is rotatable by the coupling pin (14) inside the insertion groove (12B).

(24) A bottom surface on one side of the insertion groove (12B) have a spring fixing groove (12B) having a predetermined depth, and one end (lower end) of an elastic spring (15) is inserted into the spring fixing groove (12B) by a predetermined depth and has a fixed position.

(25) On the other hand, as illustrated in FIG. 5, the lever (13) can have a push guide groove (13A) having a predetermined length in the front-rear direction at a top surface of the lever. Hence, one end of a push member (not illustrated) is accurately guided to a location by the push guide groove (13A) such that the adapter plate (20) fixed (locked) by the lever (13) can be unfixed (unlocked).

(26) In addition, a pin coupling hole (13B) having a predetermined diameter is formed to penetrate both side surfaces at one end of the lever (13), and the coupling pin (14) is inserted into the pin coupling hole (13B). An undersurface of the lever (13) has a spring fixing groove (13C) having a predetermined diameter as illustrated in FIG. 6, and the other end (upper end) of the elastic spring (15) is inserted into the spring fixing groove (13C). In this manner, the elastic spring (15) is stably fixed at a location between the insertion groove (12B) and the lever (13) to elastically support a free end (one end which is not fixed with the coupling pin (14)) of the lever (13).

(27) The adapter plate (20) is configured to be mounted on the mounting unit (11) of the slide (10) and used to mount an aiming-assist sight such as a dot-sight.

(28) As illustrated in FIG. 8, the adapter plate (20) includes a base plate (21) that has a predetermined length and comes into surface contact with the mounting unit (11) of the slide (10) and a sight (22) that is positioned at one end of the base plate (21) and is formed to project perpendicularly by a predetermined height.

(29) As illustrated in FIG. 9, an undersurface of the base plate (21) has a rail coupling groove (21A) which has a predetermined depth and is formed along a length thereof corresponding to a position of the rail unit (12) of the slide (10), and the rail coupling groove (21A) has a lever locking groove (21B) having a predetermined depth corresponding to a position of the lever (13) in a state where the adapter plate (20) is completely assembled into the mounting unit (11).

(30) In addition, the rail coupling groove (21A) is formed to have a T-shaped cross section corresponding to the shape of coupling protrusion (12A) of the rail unit (12).

(31) Additionally, the sight (22) fulfils a rear sight function in a state where a separate dot-sight is not mounted, and therefore a groove (not assigned with Reference sign) having a predetermined depth for an aimed shot may be formed at an upper central side of the sight (22) as illustrated in FIGS. 8 and 10.

(32) A push member inserting groove (23) that communicates with the rail coupling groove (21A) and the lever locking groove (21B) is formed on a side of the sight (22), and the lever (13) positioned inside on the rear side of the adapter plate (20) is exposed through the push member inserting groove (23) as illustrated in FIG. 10.

(33) In this respect, as illustrated in FIG. 11, the push member (not assigned with Reference sign) having a predetermined length can be inserted between the adapter plate (20) and the mounting unit (11) of the slide (10) through the push member inserting groove (23). As a result, the push member can press the lever (13) positioned inside such that the adapter plate (20) is unlocked, and thereby the adapter plate (20) can be detached from the slide (10).

(34) On the other hand, the base plate (21) of the adapter plate (20) can have position fixing holes or screw coupling holes formed at various positions depending on a dot-sight model. For example, as illustrated in FIG. 12, the base plate (21) of the adapter plate (20) can have four coupling holes at predetermined intervals and two position fixing holes at a predetermined interval from the coupling holes, the position fixing holes formed to project.

(35) Alternatively, adapter plates (20A and 20B) that have two coupling holes and two position fixing holes formed at predetermined intervals can be realized. Alternatively, an adapter plate (20C) that has two coupling holes and one position fixing hole can be realized. Alternatively, an adapter plate (20D) that has two position fixing holes and two coupling holes, the position fixing holes being formed to project by a predetermined height, can be realized.

(36) Although not described, the number or position of the coupling holes and the position fixing holes can be variously modified depending on various commercial models of the dot-sight.

(37) AS described above, according to the invention, the adapter plate slides to be assembled into the slide of the handgun, and thereby the adapter plate is fixed by the lever to have a fixed position. In this manner, the adapter plate can be easily and quickly assembled even without using a fastening member such as a screw.

(38) In addition, the push member is inserted into the push member inserting groove formed at the rear side of the adapter plate, and thereby the lever between the slide and the adapter plate is pressed to unlock (unfix) the adapter plate. In this manner, the adapter plate can be easily replaced according to various types of dot-sights.

(39) According to the invention, the following advantage is obtained. The adapter plate slides to be assembled into the slide of the handgun, and thereby the adapter plate is fixed by the lever to have a fixed position. In this manner, the adapter plate can be easily and quickly assembled even without using a fastening member such as a screw.

(40) In addition, the invention has another advantage in that the push member is inserted into the push member inserting groove formed at a rear side of the adapter plate, and thereby the lever between the slide and the adapter plate is pressed to unlock (unfix) the adapter plate. In this manner, the adapter plate can be easily replaced according to various types of dot-sights.
