Title: Frame of pistol

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims priority of Taiwanese Patent Application No. 108137481, filed on Oct. 17, 2019. 
     FIELD 
     The present disclosure relates to a frame of a pistol. 
     BACKGROUND 
     The Glock pistol is a semi-automatic pistol widely used in many countries. Five generations of Glock pistol had been developed since its introduction in 1980, with slight adjustment in the structure thereof for each generation. 
     A user of the Glock pistol may disassemble and replace components thereof, particularly a frame of the Glock pistol made from high-molecular weight polymer, which is relatively easy to be worn out and needs to be replaced. However, the components of the different generations of the Glock pistol may differ, for example, a slide lock spring may be in the form of a spring plate or a compression spring, and the commercially available pistol cannot simultaneously accommodate these two types of the slide lock spring. That is, when the user wants to purchase anew frame of the Glock pistol, he/she needs to pay special attention whether the specification of the frame matches the original components thereof. In addition, manufacturers of the frame of the Glock pistol need to design different molds for making different specifications of the frame, which not only increases manufacturing cost, but also increases inventory cost after completion of the manufacturing process thereof. 
     SUMMARY 
     Therefore, an object of the present disclosure is to provide a frame of a pistol that can alleviate at least one of the drawbacks of the prior art. 
     According to the present disclosure, a frame of a pistol includes a handgrip portion, an upper frame portion, and a trigger guard. The handgrip portion defines a magazine well which is configured for accommodating a magazine. The upper frame portion extends along a front-rear direction and is connected to a top end of the handgrip portion. The upper frame portion includes a barrel-receiving section distal from the handgrip portion. The barrel-receiving section includes a bottom wall, two sidewalls extending upwardly and respectively from two opposite ends of the bottom wall, two through slots respectively formed in the sidewalls for receiving two opposite ends of a slide lock of a slide mechanism of the pistol, a compression spring retaining groove formed in the bottom wall between the through slots, and a spring plate retaining groove extending forwardly from a top end of the compression spring retaining groove. The through slots extend in a top-bottom direction transverse to the front-rear direction for permitting upward and downward movement of the two ends of the slide lock therein. The trigger guard is connected to and is disposed between the handgrip portion and the upper frame portion. The trigger guard is located below the through slots.

     DETAILED DESCRIPTION 
     Referring to  FIGS. 1 to 4 , a frame  1  according to an embodiment of the present disclosure is suitable to be assembled with a slide mechanism  2 , a barrel  22 , a trigger mechanism  3 , and a magazine  4  for forming a Glock pistol. 
     The frame  1  of this embodiment includes an upper frame portion  11 , a handgrip portion  12 , and a trigger guard  13 . The upper frame portion  11  extends along a front-rear direction, and includes a barrel-receiving section  110 . The barrel-receiving section  110  includes a bottom wall  111 , two sidewalls  112  extending upwardly and respectively from two opposite ends of the bottom wall  111 , two through slots  113  respectively formed in the sidewalls  112 , a compression spring retaining groove  114  formed in the bottom wall  111  between the through slots  113 , and a spring plate retaining groove  115  extending forwardly from a top end of the compression spring retaining groove  114 . 
     The handgrip portion  12  defines a magazine well  121  which is configured for accommodating the magazine  4 , and has a top end connected to the upper frame portion  11  at a position proximate to a rear end thereof. The barrel-receiving section  110  is distal from the handgrip portion  12 . 
     The trigger guard  13  is connected to and disposed between the handgrip portion  12  and the upper frame portion  11 , and is located below the through slots  113 . 
     The slide mechanism  2  includes a slide  21 , a slide lock  23 , a slide lock spring and a slide stop lever. The slide lock spring for use in this embodiment may be a compression spring  24  or a spring plate  25 , and the slide stop lever for use in this embodiment may be a double-side slide stop lever  26  or a single side slide stop lever  27 . The double-side slide stop lever  26  has two leg portions  261  and a bight portion  262  between the leg portions  261 . The single side slide stop lever  27  has one leg portion  271 . 
     The through slots  113  of the upper frame portion  11  extend in a top-bottom direction transverse to the front-rear direction for receiving two opposite ends of the slide lock  23  and for permitting upward and downward movement of the two ends of the slide lock  23  therein. The compression spring retaining groove  114  and the spring plate retaining groove  115  are located below the slide lock  23 . A user may choose to install the compression spring  24  or the spring plate  25 . As shown in  FIGS. 5 and 6 , the spring plate  25  is inserted into the spring plate retaining groove  115 , and as shown in  FIG. 7 , the compression spring  24  is inserted into the compression spring retaining groove  114 . When the spring plate  25  is inserted into the spring plate retaining groove  115 , an end of the spring plate  25  is positioned in a notch  231  at the bottom portion of the slide lock  23  and pushes upwardly the slide lock  23  so as to provide a resilient restoring force when the slide lock  23  is compressed downwardly. Similarly, when the compression spring  24  is inserted into the compression spring retaining groove  114 , a top end of the compression spring  24  is positioned in the notch  231  at the bottom portion of the slide lock  23  and pushes upwardly the slide lock  23  so as to provide the resilient restoring force when the slide lock  23  is compressed downwardly. 
     Referring back to  FIGS. 1 to 3 , the upper frame portion  11  further includes a slide stop lever-receiving section  116  located rearwardly of the barrel-receiving section  110 . The slide stop lever-receiving section  116  includes a front receiving section ( 116   a ) proximate to the barrel-receiving section  110 , and a rear receiving section ( 116   b ) extending rearwardly from the front receiving section ( 116   a ) opposite to the barrel-receiving section  110 . The user may choose to dispose the double-side slide stop lever  26  or the single side slide stop lever  27  in the slide stop lever-receiving section  116 . When the double-side slide stop lever  26  is disposed in the slide stop lever-receiving section  116 , the bight portion  262  thereof is inserted into the front receiving section ( 116   a ) and the two leg portions  261  thereof are inserted into the rear receiving section ( 116   b ). When the single side slide stop lever  27  is disposed in the slide stop lever-receiving section  116 , the leg portion  271  thereof is inserted into the rear receiving section ( 116   b ). 
     In summary, by having the compression spring retaining groove  114  and the spring plate retaining groove  115  for receiving the compression spring  24  and the spring plate  25 , respectively, and the slide stop lever-receiving section  116  for receiving one of the double-side slide stop lever  26  and the single side slide stop lever  27 , the flexibility of using the frame  1  of the present disclosure can be enhanced. 
     While the present disclosure has been described in connection with what is considered the exemplary embodiments, it is understood that this disclosure is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
