US12584712 - Firearms with an ambidextrous slide stop and/or relief

The application pertains to 1911 style firearms. The firearms can have a relief and/or an ambidextrous slide stop. The firearm frame can have a relief to capture debris. The relief can sit below where the barrel sits once assembled with the frame. The relief can be shaped such that debris that would typically be held in the barrel void would instead fall into the relief. The firearm can have an ambidextrous slide stop. The slide stop can incorporate a male-female interlocking mechanism allowing for secure and removable coupling.

Claim 1

1 . A firearm comprising: a frame of a handgun comprising an outer surface with a first side and a second side; a slide attached slidably to the frame comprising a stop notch; wherein the frame comprises an inner surface with at least one relief configured to capture debris away from moving parts; and a slide stop attached to frame, wherein the slide stop is configured to move in and out of engagement with the slide for locking and releasing the slide, the slide stop comprising an integral first portion and an integral second portion removably attached to the frame, wherein the first portion is on the first side of the frame and the second portion is on the second side of the frame, and the first portion comprising a first lever with a proximal end and a distal end, a shaft extending perpendicularly from the distal end of the first lever, and a stopper extending from the first lever configured to mate with the stop notch, the first lever extending along the outer surface of the frame facilitating operation of the slide stop, and the second portion comprising a second lever, the slide stop further comprising a mating mechanism between the first portion and the second portion, wherein the mating mechanism comprises a male mating mechanism on the first portion and a female mating mechanism on the second portion, wherein the male mating mechanism is a tab extending from the shaft configured to mate with the female mating mechanism on the second portion, the female mating mechanism comprising an inward protrusion comprising a recess configured to receive the tab of the male mating mechanism and wherein the recess of the female mating mechanism does not extend through the second portion; and wherein the first portion and the second portion, upon mating with each other via the mating mechanism move operably with one another such that engaging the stopper with the stop notch is achievable with either hand of a user. a frame of a handgun comprising an outer surface with a first side and a second side; a slide attached slidably to the frame comprising a stop notch; wherein the frame comprises an inner surface with at least one relief configured to capture debris away from moving parts; and a slide stop attached to frame, wherein the slide stop is configured to move in and out of engagement with the slide for locking and releasing the slide, the slide stop comprising an integral first portion and an integral second portion removably attached to the frame, wherein the first portion is on the first side of the frame and the second portion is on the second side of the frame, and the first portion comprising a first lever with a proximal end and a distal end, a shaft extending perpendicularly from the distal end of the first lever, and a stopper extending from the first lever configured to mate with the stop notch, the first lever extending along the outer surface of the frame facilitating operation of the slide stop, and the second portion comprising a second lever, the slide stop further comprising a mating mechanism between the first portion and the second portion, wherein the mating mechanism comprises a male mating mechanism on the first portion and a female mating mechanism on the second portion, wherein the male mating mechanism is a tab extending from the shaft configured to mate with the female mating mechanism on the second portion, the female mating mechanism comprising an inward protrusion comprising a recess configured to receive the tab of the male mating mechanism and wherein the recess of the female mating mechanism does not extend through the second portion; and wherein the first portion and the second portion, upon mating with each other via the mating mechanism move operably with one another such that engaging the stopper with the stop notch is achievable with either hand of a user.
