An improved M1911 handgun is disclosed. The improved M1911 handgun contains a handle containing a lower end, and a magazine well formed in the handle and adapted to receive and hold a double stacked magazine, wherein the inner cross-sectional profile of the magazine well is same from the lower end of the handle to a top of a frame of the improved M1911 handgun.

An unfinished firearm frame having a top adapted to receive a slide. Where rear restriction protrusions extend from the top of the frame near a rear of the frame which restricts addition of the slide to the frame and front restriction protrusions extend from the top of the frame and forward of the at least one rear restriction protrusion which restricts addition of the slide to the frame. Where there is a recoil assembly block adapted to prevent a recoil assembly from being assembled into the frame. A jig having a right side and a left side to receive and clamp the frame. The jig including three pin hole guides, a removal guide edge for each of the at least one rear restriction protrusion and the at least one front restriction protrusion and a recoil assembly cutout to allow a tool to pass to the recoil assembly block.

Provided is a method that includes determining a device geolocation based on a satellite signal received by a weapon-tracking device and receiving a sensor reading using a sensor attached to the weapon-tracking device, wherein the sensor is sensitive to a use of the weapon. The instructions include determining that a change in the sensor reading satisfies a change threshold and, in response to a determination that the change threshold is satisfied, transmitting device state data to a wireless signal receiver via a wireless signal, wherein the device state data comprises a device identifier and the device geolocation. The instructions further include storing the device identifier and the device geolocation in a data server in communication with the wireless signal receiver and transmitting a message based on the device identifier and device geolocation to a client from the data server.

An assembly for a modular, compact firearm includes a universal action and an interchangeable, non-reciprocating barrel. The barrel may directly mount various optical sighting systems and provide integral muzzle compensation and sound suppression capabilities. The firearm utilizes a universal action comprised of a slide assembly, breechblock assembly, recoil assembly, and receiver which mounts a variety of barrel assemblies and assembles into a variety of different grip frames. The action of the firearm utilizes a partially-locked breechblock which amplifies the inertia of a slide.

A handgun offhand finger rest apparatus for comfort and support when using the offhand for recoil management includes an attachment body having a body top side, a body bottom side, a body left side, a body right side, a body front side, and a body back side. The body top side is selectively engageable with an underside of a firearm in front of a trigger guard of the firearm. A thumb rest is coupled to the attachment body and perpendicularly extends from either the body left side or the body right side. A finger rest is coupled to the body bottom side of the attachment body adjacent the body back side to rest adjacent the trigger guard of the firearm.

Apparatus and associated methods relate to a handgun brace arranged with a rigid structure extending radially away from a handgun trigger guard, and having a forward-facing surface configured to physically engage with at least one finger of a user's non-primary grip hand in a stable position below the handgun's barrel and in front of the handgun's trigger, such that a counter-force applied by the finger(s) at the forward-facing surface tends to prevent the handgun (especially the muzzle), from rising or rotating in response to shooting, such as due to muzzle jump. In an illustrative example, the brace may be releasably fixed to the handgun (e.g., as a modular handgun accessory). A handgun brace that substantially mitigates the unwanted effects of muzzle jump/recoil may advantageously yield higher shooting accuracy and beneficially promote proper handgun grip positioning.
