   DETAILED DESCRIPTION OF THE INVENTION 
     FIG. 1  illustrates a holster  10  containing a holstered handgun  11  in interior cavity  13  formed by holster body  12 . Body  12  is a rigidly molded structure with an interiorly disposed portion  14  adjacent the ejection port of handgun  11  or any other surface that can be engaged to inhibit withdrawal of the handgun  11 . 
   The interior cavity  13  of the holster  10  is molded for a specific model of handgun  11  and includes space for a spring-loaded ejection port locking device shown generally at  18  in  FIGS. 2-7   
   The specific locking device  18  shown in  FIGS. 2-7  is mounted via mounting posts  22  extending outwardly from mounting arms  21  of body  19  that fit within mounting holes  16  of holster  10 . An alternate construction of a locking device will be discussed hereinbelow. An integrally formed operating lever  20  has a thumb pad  24  on an end thereof. 
   The body or saddle  19  of locking device  18  is formed to engage upward surfaces of a specific handgun  11  to position the gun properly in the holster and includes an interiorly disposed ejection port indexing edge  26  that fits against respective front edge  27  of the right-side ejection port  29  of handgun  11  ( FIG. 10 ). Preferably, an opposed pair of spaced indexing edges  30 , 31  are also molded into device body  19  to fit against a handgun to also assist in positioning the gun with respect to the device  18 . 
   When locking device  18  is secured inside holster  10 , it will rest slightly below the mating surface created by molded cavity  17 . As will be described in more detail below, the insertion of handgun  11  into holster cavity  13  against angled locking saddle surface  23  will cause the locking device  18  to be pushed into cavity  17  forcing locking edge  26  into ejection port  29  and against locking front edge  27 . From this position it will be necessary to move the locking edge  26  away from ejection port  29  to withdraw a handgun  11  upwardly out of the holster. The angled locking saddle surface  23  may be defined as at least one sloping surface to guide the handgun into its proper seated position in the holster. 
   From the directions referenced in  FIG. 1 , rearward movement of operating arm  20  by pressure on thumb pad  24  will cause the main body  19  of device  18  to pivot about post axis  22 A toward cavity  17 . The locking edge  26  will move away from port edge  27  a sufficient distance to allow the handgun  11  to be withdrawn from the holster  10 . Forward spring element or spring member  19 A is bendable around pivot portion  19 B as operating lever arm  20  is pushed rearwardly causing body  19  to move away from handgun  11 . The member  19 A normally rests against the interior surface of molded cavity  17  and applies a rearward force onto the handgun while the positioning member or tension device  32  maintains proper positioning of the handgun  11  in the holster cavity  13 . 
   An adjustable tension device (ATD)  32  is fixed to the interior cavity  13  of the holster  10 . As handgun  11  is inserted into holster  10 , the handgun  11  will come into contact with an angled funneling surface portion  33  of ATD  32  and position the handgun  11  against the locking device  18  to place the locking surface  26  of device  18  into contact with ejection port  29  of handgun  11 . The handgun  11  will be locked into place with locking edge  26  against edge  27  of port  29 . Tension device only is for muzzle location and applying tension on the holstered pistol, i.e., to give resistance during draw of handgun and take up loose play between pistol and holster. 
   With respect to  FIGS. 8-12 , a second embodiment of a spring-loaded ejection port lock  34  is illustrated. A mounting pad  35  includes a hole  36  therethrough for passage of a fastener to rigidly affix lock device  34  to the interior cavity  13  of a holster  10 . Mounting holes  16  ( FIG. 1 ) would not be formed in the holster when using lock device  34 . 
   Pad member  35  is part of a forward lever  39  that is movable about a first pivot portion  40 . A second spring member  37  is movable about a second pivot portion  38 . An operating arm  41  has a thumb pad  42  adjacent a hook member  43  used to movably position arm  41  to a portion of holster body  12  as clearly shown in partial cross-section in  FIG. 9 . 
   The upper surfaces of the main body  45  of locking device  34  fit spaced away from a molded cavity  44  that is formed to accommodate the lock  34  in a manner similar to the fitting of lock  18  into cavity  17 . Spring lever arm  37  fits within cavity  44  (as shown by bulge  48  in  FIG. 1 ). 
     FIGS. 8-12  illustrate the arrangement of the ejection port lock  34  with respect to a specific handgun  11 . Interior surfaces  46  include a locking surface  47  usable against an ejection port in a manner substantially identical to that described hereinabove with respect to  FIG. 1-7 . 
     FIGS. 13-14  illustrate the adjustable tension device  32 . Body  49  is preferably formed of hard plastic material and is mounted via hole  52  to holster  10  and includes a camming surface  50  integral with an arm member  50 A and which is movable slightly upwardly by a screw  53  mounted in threaded hole  54 . Member  51  provides a travel limit for screw  53 . Upper surface  55  is adjusted via screw  53  to contact the handgun  11 . Rearward surface  56  contacts the trigger guard of a handgun  11  and functions as a gun travel limit. Lower surface  57  rests against the spine of a holster  10 . 
     FIGS. 15-17  illustrate another embodiment of a locking device  58 . With the exception of forward extension arm  59  the device  58  is identical to the lock  34 . Extension arm  59  includes an enveloping hood  60  at the end  61  thereof. Hood  60  fits against the radiused detail  62 A on weapon  62  or the forward muzzle sight of a handgun  62  to hold the gun in the holster  11 . 
   Lock device  58  is employed for certain firearms that do not include a sufficient locking surface adjacent the main body or saddle  45 , for example the firearm depicted in  FIG. 22 . Thus the lock device  58  need not include locking edges  26  and  47  but will include a forward locking surface, such as  64 A or  66 A. 
   With respect to  FIG. 18 , another embodiment of a locking device  63  is shown in perspective. The lock  63  is substantially identical to lock device  34  with the exception of extension arm  64  which includes sloping surface  64 B. Oval boss  64 A fits within an oval-shaped lightening cut  79  and engaging shoulder  80  formed on Glock  78  ( FIG. 23 ). 
     FIGS. 19-20  illustrate another locking device  65  that is substantially identical to the device  34  with exception of the extension arm  66  and locking surface  66 A, which is used with a particular firearm such as a Berretta  76  ( FIG. 22 ). 
   Each of the locking devices disclosed hereinabove operates in the following manner. Each locking device has a forward portion with upper and lower surfaces and a rear portion with a pivot point between. The forward portion is pressed downwardly on a handgun in a holster and positively engages the gun at some area (such as ejection ports) to lock the gun in the holster to inhibit withdrawal of the gun. The lower surface of the saddle position includes angled or sloping surfaces which position the device over the gun slide and to center the device by directing movement of the handgun. Pressure on a rearward lever-operating arm causes the forward gun-engaging portion of the device to move away from the gun. The pivoting of the forward portion is around the mounting axle axis of device  18  or around a pivot area such as area  40  of devices  34 ,  58 ,  63  and  65 . Spring members on the front of the device provide a means to push the device onto the gun but in a manner that allows for spacing between the locking portion body or saddle and the mating surface located in the front portion of the holster which provides sufficient space for unlocking the device from the gun by moving the locking portion body away from the locking features of the holstered firearm. The adjustable tension device such as  32  is provided to assist in positioning the gun in the holster to provide for proper engagement between the handgun and the locking device. 
   The exact dimensions of the locking devices and mating surfaces depend on the specific handgun involved. 
   If the holster  10  used has an open muzzle end, the preferred tension device used will be the device  67  mounted in the holster by a screw passing through opening  70 , illustrated in  FIG. 21 . The gun contacting surface  68  is integral with arm member  72  carrying a camming surface  73 . Camming surface  73  is in contact with adjustment screw  74  threaded through passageway  75 . Bottom surface  71  rests against the spine or rearward portion of a holster  10 . A gun-contacting surface  76  contacts the trigger guard of a handgun and provides a travel limit for a handgun  11  in holster  10 . Adjustment screw  74  is accessible through an open muzzle end of a holster  10  thus making adjustments faster and more convenient. 
   A number of other devices such as rollers and wedge-shaped blocks can be used in lieu of ATD&#39;s  32  and  67 . ATD&#39;s  32 ,  67  are preferred devices because they are adjustable in order to provide a correct positioning of the handgun and the locking devices discussed herein. 
   The forward spring members, such as member  19 A, are shown as integral plastic elements, it is important to note that the spring members may in fact be other devices such as coil springs that are attached to the main body of a given locking device. In addition, operating arms are also shown as integral with the locking device body of a particular embodiment. It is to be understood that such arms can be separate members attached to the device body by any appropriate means. 
   The devices shown in  FIGS. 1-20  are designed for a right-hand draw. Devices for a left-hand draw are mirror images of respective right-hand devices and are otherwise substantially identical in structure and operation. 
   While the invention has been described with respect to certain specific embodiments, it will be appreciated that many modifications and changes may be made by those skilled in the art without departing from the true spirit of the invention. It is intended therefore, by the appended claims to cover all such modifications and changes as fall within the true spirit and scope of the invention.
