For example, the steps recited in any of the method or process descriptions may be executed in any order and are not necessarily limited to the order presented. Furthermore, any reference to singular includes plural embodiments, and any reference to more than one component or step may include a singular embodiment or step. Also, any reference to attached, fixed, connected or the like may include permanent, removable, temporary, partial, full and/or any other possible attachment option.

Additionally, any reference to without contact (or similar phrases) may also include reduced contact or minimal contact.

[0013] The present disclosure is directed to a trigger for a striker fired firearm like the pistol manufactured by Glock, Inc. The trigger is generally configured to improve the ballistic the performance and user experience when operating a striker fired firearm.

[0014] In various embodiments and with reference to Figs. 1 A - 1C, a striker fired firearm 100 may comprise a frame 110, a slide 120, a barrel 130, and a trigger 140. Firearm 100 may also comprise a firing pin system 125 and a recoil system 135. Barrel 130 may be slidably installed in slide 120. Firing pin system 125 may be installed in and may be retained in slide 120. Recoil system 135 may also be installed in slide 120. Slide 120 may be slidably installed on frame 110. Trigger 140 may be installed in frame 110. Trigger 140 may be configured to operatively engage firing pin system 125. Firing pin system 125 may comprise a tab 127. Tab 127 may be engageable by trigger 140.

[0015] In various embodiments and in operation, firing pin system 125 may be held in a first position (e.g., battery position or a ready to fire position) and may be actuated to a second position (e.g., a firing position) in response to the actuation of trigger 140. Trigger 140 may be movable or actuatable by a user between a first position and a second position.

The movement between the first position and the second position allows the firing pin system to move forward and strike a round of ammunition in barrel 130.

[0016] In various embodiments and with reference to Figs. 2A-2B, trigger 140 may comprise a trigger bar or elongate body 142, a shoe 144 and a sear pack 150. Elongate body 142 may comprise a shoe connector 146. Shoe connector 146 may be operatively coupled to or formed in an end (e.g., a second end) of elongate body 142. Shoe connector 146 may be disposed at an angle relative to elongate body 142 (e.g., an angle relative to the longitudinal axis of elongate body 142). Elongate body 142 may comprise a sear arm 148. Sear arm 148 may be operatively coupled to or formed in an end (e.g., a first end) of elongate body 142. Sear arm 148 may be disposed at an angle substantially perpendicular to elongate body 142 (e.g., substantially perpendicular relative to the longitudinal axis of elongate body 142).

[0017] In various embodiments, shoe 144 may be coupled to elongate body 142. Sear arm 148 may be configured to operatively engage sear pack 150.

[0018] In various embodiments, sear pack 150 may comprise a sear 152 and a housing 154. Sear pack 150 may also comprise a pin 156. Sear 152 may be installable in sear housing 154. Sear 152 may be retained in sear housing 154 by pin 156. Sear 152 may be rotatable in housing 154 about pin 156. Sear 152 may comprise a first end and a second end.

[0019] In various embodiments, housing 154 may include a spring channel 157 and a spring 158. Spring channel 157 may be defined in housing 154 such that it is below sear 152 when sear 152 is installed in housing 154. Spring 158 may be installed in spring channel 157. Spring 158 may be configured to operatively engage sear 152. Spring 158 may be configured to bias or load sear 152 in a first direction (e.g., bias or load sear 152 up). In this regard, spring 158 is configured to bias or load sear 152 against firing pin system 125. Moreover, spring 158 may be configured to load retaining arm 153 against tab 127 or firing pin system 125 as shown in Fig. IB.

[0020] In various embodiments, sear pack 150 may also comprise a travel limit pin 159. The motion of sear 152 may be limited by travel limit pin 159. Sear 152 may include a travel hole defined through the body of sear 152 proximate the second end of sear 152.

Travel limit pin 159 may be installable in housing 154 through the travel hole of sear 152. Travel hole may be sized to limit the rotation of sear 152 to facilitate the operation of reset of firearm 100. In this regard, the diameter of the travel hole may be larger than the outer diameter of travel limit pin 159.

[0021] In various embodiments and in operation, spring 158 may bias or load sear 152 in a first direction toward the firing pin system. In response to actuation of trigger 140, the translates to the rear of firearm 100, forcing sear 152 to rotate about pin 156 and compressing spring 158. The rotation of sear 152 causes retaining arm 153 to release tab 127 of firing pin system 125, allowing the firing pin to strike a round of ammunition.

[0022] In various embodiments and with reference to Fig. 2C, elongate body 242 of trigger 240 may comprise a sear arm 248 that includes a that includes an engagement tab. The engagement tab may be “U” shaped. The engagement tab may engage sear pack 250. In this regard, the engagement tab may be sized to engage and/or surround retaining arm 253 of sear 252. Moreover, the engagement tab my be configured to limit lateral motion of sear 252. The engagement tab may also be configured to limit the lateral motion of elongate body 242.

[0023] In various embodiments and with reference to Fig. 3, trigger 340 may be installable in frame 310. Shoe 344 may pass through frame 310 so that it is accessible to the user. As discussed herein, shoe 344 is operatively coupled to the trigger bar or elongate body 342 via shoe connector 346. Housing 354 of sear pack 350 is installable in frame 310. Sear 352 is engageable and actuatable by the sear arm 348.

[0024] In various embodiments and with reference to Fig. 4A - 4B, sear pack 450 may be installable in connector 112 of the frame of the firearm. Pin 456 and travel limit pin 459 may fit flush in housing 454. In this regard, there is no interference between the connector cavity and sear pack 450. Sear pack 450 and, more specifically, housing 454 may be retained in connector 112 with housing screw 460. During installation, housing 454 may be positioned in connector 112 and secured to connector 112 by tightening housing screw 460. Sear 452 may protrude above housing 454 and connector 112 such that trigger 440 and, more specifically, trigger bar or elongate body 442 and sear ram 448 may actuate sear 452.

[0025] In various embodiments and with reference to Figs. 5A-5B, sear pack 550 may have housing 554 comprising a pin 556 (e.g., a single pin). Pin 556 may be installable through sear 552. Sear 552 may be rotatable about pin 556 in response to being engaged or actuated by sear arm 548 of the trigger. Sear 552 may comprise a sear stop 559. Sear stop 559 may be configured to limit the rotational motion of sear 552 about pin 556. Sear stop may be configured to contact or engage one or more surface of housing 554 to limit the range of motion or rotation of sear 552. Housing 554 may also comprise a spring channel 557 and a spring 558 that is configured to load or bias sear 552 as discussed herein.

[0026] In various embodiments and with reference to Fig. 6, sear 652 may comprise a sear arm catch 662. Sear arm catch 662 may be configured to engage sear arm 648 when sear arm 648 is in a first position. Sear arm 648 may be actuated out of engagement with sear arm catch 662 causing sear 652 to rotate. Sear 652 may rotate to compress spring 658 in spring channel 657, until it contacts travel limit pin 656 or a sear stop.
