[0002] 1. Technical Field

[0003] The present invention, in some embodiments thereof, relates to a slide pull that fits on a semi-automatic pistol, and, more particularly, but not exclusively, to a slide pull that fits on a Glock semi-automatic pistol.

[0004] 2. Discussion of the Related Art

[0005] Glock is the name of a family of popular semi-automatic pistols designed and produced by the Austrian company Glock GmbH or Deutsch-Wagram. A typical Glock semi-automatic pistol has a 9 mm short recoil-operated locked breech.

[0006] The Glock semi-automatic pistol, while a popular hand weapon, may pose some difficulties for a user. To cock the pistol for the first shot, the spring-loaded slide must be pulled toward the user. A professional, for example a policeman often pulls the slide with the palm of the opposite hand to the hand on the pistol grip in a single motion as the Glock is pulled from a side holster.

[0007] An occasional user, for example teenagers and women at a target range, may hold the pistol while tracking a target and use the thumb and index finger of the opposite hand to pull back the Glock slide. It is difficult to pull the spring-loaded slide with the thumb and index fingers. Additionally, this style of pull the slide often causes the hand grasping the pistol to move, causing time wastage as the user retrains the pistol on the target; or inaccuracy in hitting the target.

[0008] According to an aspect of some embodiments of the invention, there is provided a slide pull apparatus for aiding in pulling a slide on a semi-automatic pistol, the slide pull apparatus comprising a shell configured to partially enclose a rear portion of a slide on a semi-automatic pistol. In embodiments, the shell includes a plate having an aperture of a size configured to surround at least a portion of a rear aim sight on the semi-automatic pistol. Additionally the shell includes two sidewalls extending downward from the plate, each of the two sidewalls having an inner surface configured to each rest against a side portion of a slide of the semi-automatic pistol, wherein pulling on the slide pull in a rearward direction causes the slide to move in a rearward direction, thereby facilitating loading of the semi-automatic pistol.

[0009] According to some embodiments of the invention, the apparatus includes at least one finger tab projecting from the shell, the finger projection having a size configured to accommodate at least one finger of a human hand.

[0017] According to some embodiments of the invention, the inner surface of each of the two sidewalls includes at least one rib configured to offset at least a portion of the respective sidewall from the slide of the semi-automatic pistol.

[0018] According to some embodiments of the invention, the at least one finger tab projects laterally outward from at least one outer surface of the two side walls.

[0019] According to some embodiments of the invention, the at least one finger pull comprises two finger pulls, each projecting laterally outward from a respective outer surface of one of the two sidewalls.

[0020] According to still another aspect of some embodiments of the invention, there is provided a slide pull apparatus for aiding in pulling a slide on a semi-automatic pistol, the slide pull apparatus comprising a shell configured to partially enclose a rear portion of a slide on a semi-automatic pistol, the shell including: a plate having an aperture of a size configured to surround at least a portion of a rear aim sight on the semi-automatic pistol, two sidewalls extending downward from the plate, each of the two sidewalls having an inner surface having a projection configured to each rest against a side portion of a slide of the semi-automatic pistol, and one finger tab projecting laterally outward from an outer surface of each of the sidewalls, the finger projection having a size configured to accommodate at least one finger of a human hand, wherein pulling on at least one finger tab in a rearward direction causes the slide to move in a rearward direction, thereby facilitating loading of the semi-automatic pistol.

[0021] Unless otherwise defined, all technical and/or scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the invention pertains. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of embodiments of the invention, exemplary methods and/or materials are described below. In case of conflict, the patent specification, including definitions, will control. In addition, the materials, methods, and examples are illustrative only and are not intended to be necessarily limiting.

[0027] The present invention, in some embodiments thereof, relates to assemblies that convert a semi-automatic hand pistol into a rifle, and, more particularly, but not exclusively, to an assembly that converts a Glock semi-automatic pistol into a rifle.

[0028] Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways.

[0029] Referring to FIG. 1, before firing a bullet 74 from a Glock semi-automatic pistol 90, herein Glock 90, a slide 70 must be pulled back in a first direction 80 to allow bullet 74 to move into a barrel 72 from a magazine 76, which is located in a pistol grip 79. Slide 70 and barrel 72 then move forward in a direction 82 and Glock 90 is ready to be fired.

[0030] After a trigger 78 is pulled, barrel 72 moves rearward, initially locked together with slide 70 until bullet 74 leaves barrel 72 through an ejection passage. Barrel 72 then unlocks from slide 70.

[0031] During continued backward movement of slide 70, barrel 72 tilts slightly in preparation for receiving another bullet 74.

[0032] Slide 70 continues uninterrupted movement backward in direction 80 under recoil power, extracting and ejecting the spent cartridge of bullet 74, allowing a second bullet 75 to move via spring action to align with barrel 72.

[0033] The next bullet 74 automatically enter barrel 72 during recoil of Glock 90 without pullback of slide 70 until the shooting session has finished or magazine 76 has been emptied of bullets 74.

[0034] FIG. 2 shows a slide case 100 mounted on a schematic drawing of pistol 90. A rear aim sight 84 extends into a rear aim sight aperture 110, thereby locking slide case 100 in position along slide 70.

[0035] FIGS. 3-4, to better appreciate some of the details of slide case 100 shown in schematic views, show Glock pistol 90 in schematic and plan views respectively.

[0036] For example, a ledge 122 fits above the lower edge of slide 70 when slide case 100 is placed in position on Glock 90 according to dashed lines 126 (FIG. 3). Additionally slide case 100 includes an indentation 124 to accommodate the profile of the rear portion of slide 70.

[0037] Ribs 130 on side walls 134 create a distance between pistol corrugations 132 (FIG. 4) and allow ventilation of Glock 90 when slide casing is positioned on Glock 90, as indicated by an arrow 140.

[0038] While three ribs 130 are shown, slide case 100 may have as few as one rib on each side wall 134, or as many as about 10 on each side wall.

[0039] Side case lateral flanges 120 act as finger grips, alternatively referred to as “finger tabs”, with which a user pulls slide casing 100, together with slide 91 in rearward direction 80, thereby allowing first bullet 74 to enter barrel 72.

[0040] Thereafter, the next bullet 75 automatically enter barrel 72 during recoil of Glock 90 as noted above.

[0041] It is expected that during the life of a patent maturing from this application many relevant slide pulls will be developed and the scope of the term slide pull is intended to include all such new technologies a priori.

[0042] The terms “comprises”, “comprising”, “includes”, “including”, “having” and their conjugates mean “including but not limited to”.
